+# Signal CLI REST API Deployment
+
+## Overview
+Signal CLI REST API deployed in the `connections` namespace, accessible at `connections.local.mk-labs.cloud` with automatic TLS certificate management.
+
+## Infrastructure Details
+
+### Namespace
+- **Name**: `connections`
+- **Theme**: EPCOT Connections (Communication & World Showcase)
+
+### Deployment
+- **Name**: `signal-cli-rest-api`
+- **Image**: `bbernhard/signal-cli-rest-api:0.85`
+- **Replicas**: 1 (MUST be 1 - signal-cli state is not multi-instance safe)
+- **Strategy**: Recreate (prevents dual mount of PVC)
+- **Mode**: json-rpc
+
+### Service
+- **Name**: `connections`
+- **Type**: ClusterIP
+- **Port**: 8080
+- **Selector**: `app.kubernetes.io/name: signal-cli-rest-api`
+
+### Ingress
+- **Name**: `connections`
+- **Class**: nginx
+- **Hostname**: `connections.local.mk-labs.cloud`
+- **TLS**: Enabled with cert-manager
+- **Certificate**: Auto-provisioned via Let's Encrypt (letsencrypt-prod ClusterIssuer)
+- **DNS Challenge**: Cloudflare DNS-01
+
+### Storage
+- **PVC**: `signal-cli-data`
+- **Mount Path**: `/home/.local/share/signal-cli`
+
+## ArgoCD Deployment
+
+### Application
+- **Name**: `signal-cli`
+- **Namespace**: `argocd`
+- **Sync Wave**: 8
+- **Source Path**: `cluster/applications/signal-cli/`
+- **Auto Sync**: Enabled
+- **Auto Prune**: Enabled
+- **Self Heal**: Enabled
+
+## SSL/TLS Status
+
+### External Access (Ingress)
+✅ **Working** - TLS certificate successfully issued by Let's Encrypt
+- Certificate CN: `connections.local.mk-labs.cloud`
+- Issuer: Let's Encrypt (YR2)
+- Valid until: September 10, 2026
+- DNS-01 challenge completed successfully via Cloudflare
+
+### Signal Server Communication
+✅ **Working** - No SSL errors detected
+- Signal-cli uses Java's built-in truststore (OpenJDK 21)
+- Java truststore includes Signal's CA certificates
+- No custom CA injection needed
+
+### Note on curl SSL Errors
+The initial SSL error encountered with curl was due to the system CA bundle being outdated in the container. This does NOT affect signal-cli functionality because:
+1. Signal-cli uses Java's truststore, not the system CA bundle
+2. Java's truststore is properly maintained and includes Signal's root CA
+3. All signal-cli operations work correctly without SSL errors
+
+## Endpoints
+
+### Health Check
+```bash
+GET https://connections.local.mk-labs.cloud/v1/health
+```
+
+### About/Version
+```bash
+GET https://connections.local.mk-labs.cloud/v1/about
+```
+
+Expected response:
+```json
+{
+  "versions": ["v1", "v2"],
+  "build": 2,
+  "mode": "json-rpc",
+  "version": "0.85",
+  "capabilities": {
+    "v2/send": ["quotes", "mentions"]
+  }
+}
+```
+
+## Migration from cluster/platform/connections
+
+Files were moved from `cluster/platform/connections/` to `cluster/applications/signal-cli/`:
+- ✅ namespace.yaml
+- ✅ deployment.yaml
+- ✅ service.yaml
+- ✅ persistentvolumeclaim.yaml
+- ✅ application.yaml (updated source path)
+- ✅ ingress.yaml (newly created)
+
+## Current Status
+
+**Production Gateway**: astro-orbiter VM (10.1.71.130:8080)
+- signal-cli 0.14.3 native daemon mode with HTTP JSON-RPC API
+- Account +126****8840 registered and operational
+- Hermes connected via SIGNAL_HTTP_URL=http://10.1.71.130:8080
+
+**K8s Deployment Status**:
+- ✅ Infrastructure deployed and ready (ingress, PVC, service)
+- ✅ Native signal-cli daemon running in multi-account mode
+- ✅ Ingress accessible at https://connections.local.mk-labs.cloud
+- ❌ Cannot complete Signal registration from K8s network path
+  - Linking fails with "Connection closed unexpectedly" during WebSocket handshake
+  - Signal servers reject connections from K8s cluster (HTTP 499, same on all nodes)
+  - Issue persists with hostNetwork=true
+  - Likely NAT/firewall/IP reputation blocking Signal WebSocket connections
+
+**When Migrating from Astro-Orbiter**:
+1. Link account from a non-K8s VM (e.g., carousel-of-progress)
+2. Copy working signal-cli data to K8s PVC
+3. Update Hermes: SIGNAL_HTTP_URL=https://connections.local.mk-labs.cloud
+4. Restart Hermes gateway
+
+## Next Steps
+
+1. **Investigate K8s egress networking** - why Signal rejects WebSocket connections from cluster
+2. **Alternative**: Keep Signal gateway on dedicated VM outside K8s
+
+## Monitoring
+
+Check deployment status:
+```bash
+kubectl get all,ingress,certificate -n connections
+```
+
+Check ArgoCD sync status:
+```bash
+kubectl get application signal-cli -n argocd
+```
+
+View logs:
+```bash
+kubectl logs -n connections deployment/signal-cli-rest-api -f
+```

+# Portworx CSI Deployment Checklist
+
+Pre-deployment checklist for Portworx CSI driver on Talos Linux with Pure Storage FlashArray.
+
+## Phase 1: FlashArray Preparation
+
+- [ ] **Create FlashArray storage admin user**
+  - Username: `portworx-csi`
+  - Role: Storage Admin
+  - Password: Set in FlashArray UI
+
+- [ ] **Generate FlashArray API token**
+  - User: `portworx-csi`
+  - Expiration: None (non-expiring)
+  - Token format: `XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX`
+  - **Save token immediately** (cannot be retrieved later)
+
+- [ ] **Verify FlashArray management endpoint**
+  - Test connectivity: `ping flasharray.mk-labs.cloud`
+  - Test HTTPS: `curl -k https://flasharray.mk-labs.cloud`
+  - Record IP/hostname: _______________________
+
+- [ ] **Configure iSCSI targets on FlashArray**
+  - Navigate to: **Settings → Network**
+  - Verify iSCSI interfaces are enabled
+  - Test discovery from Talos node:
+    ```bash
+    talosctl -n <node> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
+    ```
+
+- [ ] **(Optional) Enable FlashArray File Services for NFS**
+  - Enable File Services: **Settings → File Services**
+  - Create filesystem: `fastpass-nfs`
+  - Create NFS policy with user mapping **disabled**
+  - Record NFS endpoint: _______________________
+
+## Phase 2: 1Password Secret Configuration
+
+- [ ] **Create 1Password item**
+  - Vault: `homelab`
+  - Item name: `pure-flasharray-fastpass`
+  - Category: Secure Note or API Credential
+
+- [ ] **Add pure.json field to 1Password item**

+      {
+        "MgmtEndPoint": "flasharray.mk-labs.cloud",
+        "APIToken": "paste-api-token-here",
+        "NFSEndPoint": "flasharray-nfs.mk-labs.cloud"
+      }
+    ]
+  }
+  ```
+  - Replace `flasharray.mk-labs.cloud` with actual endpoint

+    namespace: default
+  spec:
+    containers:
+    - name: test
+      image: nginx:latest
+      volumeMounts:
+      - name: data
+        mountPath: /data
+    volumes:
+    - name: data
+      persistentVolumeClaim:
+        claimName: test-pure-block
+  EOF
+  ```
+
+- [ ] **Verify pod is running**
+  ```bash
+  kubectl get pod test-pure-block-pod
+  # Expected: STATUS=Running
+  ```

+  kubectl exec test-pure-block-pod -- \
+    sh -c 'echo "test data" > /data/test.txt'
+  
+  kubectl exec test-pure-block-pod -- cat /data/test.txt
+  # Expected: "test data"
+  ```
+
+- [ ] **Verify iSCSI session established**
+  ```bash
+  # On node running test pod
+  talosctl -n <node-ip> exec -- iscsiadm -m session
+  # Expected: Active iSCSI session to FlashArray
+  ```
+
+- [ ] **Clean up test resources**
+  ```bash

+4. [ ] Delete CRDs (if needed):
+   ```bash
+   kubectl delete crd storageclusters.core.libopenstorage.org
+   ```
+
+5. [ ] Revert Talos configuration (if needed):
+   ```bash
+   # Remove portworx-csi patches from talconfig.yaml
+   talhelper genconfig
+   talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
+   ```
+
+## Success Criteria
+
+Deployment is successful when:
+
+- [ ] All pods in `portworx` namespace are Running
+- [ ] StorageClasses `pure-block` and `pure-file` are available
+- [ ] Test PVC successfully binds to a PV

+## GitOps Workflow
+
+### Deployment Flow
+```
+1. Commit to Git (homelab repo)
+   ↓
+2. ArgoCD detects changes
+   ↓
+3. Wave 2 sync (after External Secrets)
+   ↓
+4. Helm deploys Portworx Operator
+   ↓
+5. Operator deploys PX-CSI components
+   ↓
+6. StorageClasses become available
+   ↓
+7. Applications can provision volumes
+```
+
+### Dependencies
+- **Wave 1**: External Secrets Operator, 1Password Connect
+- **Wave 2**: Portworx CSI (this deployment)
+- **Wave 3+**: Applications using Pure storage
+
+## Prerequisites Summary
+
+### FlashArray Requirements
+1. ✅ FlashArray accessible from cluster network
+2. ✅ Storage admin user created with API token
+3. ✅ iSCSI targets configured (for block storage)
+4. ✅ File Services enabled (optional, for NFS)
+5. ✅ NFS policy configured with user mapping disabled (optional)
+
+### Kubernetes Requirements
+1. ✅ Talos Linux cluster with kernel modules (iscsi_tcp, dm_multipath)
+2. ✅ External Secrets Operator installed (wave 1)
+3. ✅ ClusterSecretStore configured for 1Password
+4. ✅ ArgoCD installed and operational
+5. ✅ Multipath and udev rules configured on all nodes
+
+### 1Password Requirements
+1. ✅ Vault: `homelab`
+2. ✅ Item: `pure-flasharray-fastpass`
+3. ✅ Field: `pure.json` with FlashArray configuration
+
+## Next Steps
+
+### 1. Before Deployment
+- [ ] Create FlashArray storage admin user and API token
+- [ ] Add FlashArray credentials to 1Password
+- [ ] Apply Talos configuration to all worker nodes:
+  ```bash
+  cd ~/git/homelab/talos/talhelper
+  # Add portworx-csi patches to talconfig.yaml
+  talhelper genconfig
+  talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
+  talosctl reboot --nodes <node-ip>
+  ```
+- [ ] Verify iSCSI and multipath on each node
+- [ ] Run validation script: `./validate-prereqs.sh`
+
+### 2. Deploy
+```bash
+cd ~/git/homelab
+git add cluster/platform/portworx-csi/
+git commit -m "Add Portworx CSI driver for Pure FlashArray"
+git push origin main
+
+# ArgoCD will auto-sync (wave 2)
+# Or manually sync:
+argocd app sync portworx-csi
+```
+
+### 3. Verify Deployment
+```bash
+# Check ArgoCD application
+kubectl get application -n argocd portworx-csi
+
+# Verify pods
+kubectl get pods -n portworx
+
+# Check StorageCluster
+kubectl get storagecluster -n portworx
+
+# Test with sample PVC (see DEPLOYMENT-CHECKLIST.md Phase 6)
+```
+
+### 4. Post-Deployment
+- [ ] Configure Prometheus/Grafana dashboards for Portworx metrics
+- [ ] Update homelab infrastructure documentation
+- [ ] Create runbook for common operations
+- [ ] Schedule follow-up review after 1 week
+
+## Key Design Decisions
+
+### Why Portworx CSI?
+- **Direct Access**: FlashArray volumes directly attached to pods (no aggregation layer)
+- **Native Integration**: Official Pure Storage support
+- **Feature Rich**: Snapshots, expansion, topology-aware provisioning
+- **Talos Compatible**: Works with Talos Linux after proper configuration
+
+### Why iSCSI (vs NVMe-oF)?
+- **Broad Compatibility**: Works on all Talos nodes without special NICs
+- **Proven**: Mature protocol with extensive documentation
+- **Upgrade Path**: Can migrate to NVMe-oF later for performance
+- **Simpler Setup**: Fewer hardware dependencies
+
+### Why Multi-Source ArgoCD Application?
+- **Consistency**: Follows homelab pattern (same as cert-manager, nfs-csi)
+- **Upstream Helm**: Use official Portworx chart, not custom forks
+- **Local Overrides**: StorageClasses and configs in Git
+- **GitOps Friendly**: All configuration is declarative
+
+### Why Wave 2?
+- **Dependencies**: Needs External Secrets (wave 1) for credentials
+- **Before Apps**: Storage must be ready before applications deploy
+- **Parallel Safe**: Can deploy alongside other platform services
+
+## Validation Results
+
+All YAML files validated successfully:
+- ✅ `application.yaml` - Valid YAML
+- ✅ `externalsecret.yaml` - Valid YAML
+- ✅ `operator-values.yaml` - Valid YAML
+- ✅ `storageclass-block.yaml` - Valid YAML
+- ✅ `storageclass-file.yaml` - Valid YAML
+- ✅ `storagecluster.yaml` - Valid YAML
+- ✅ `talos-config-reference.yaml` - Valid YAML
+
+## Important Notes
+
+### Talos Configuration
+⚠️ **CRITICAL**: The `talos-config-reference.yaml` file is **NOT** a Kubernetes resource. It documents the required Talos patches that must be applied via `talhelper` or `talosctl`. Do not attempt to `kubectl apply` this file.
+
+### Secret Management
+The FlashArray API token is stored in 1Password and synced to Kubernetes via External Secrets Operator. Never commit credentials to Git.
+
+### Node Reboots Required
+After applying Talos configuration with kernel modules, nodes **must be rebooted** for modules to load. Schedule appropriately.
+
+### iSCSI Initiator Names
+Each Talos node must have a **unique** iSCSI initiator name. Verify uniqueness across all nodes to avoid conflicts.
+
+### Default StorageClass
+Neither `pure-block` nor `pure-file` is set as the default StorageClass. The existing `nfs-emporium` remains the default. Applications must explicitly request Pure storage by specifying `storageClassName`.
+

+kubectl logs -n portworx -l app=portworx-operator --tail=100
+
+# PX-CSI Controller
+kubectl logs -n portworx -l app=px-csi-controller --tail=100
+
+# PX-CSI Node driver (specific node)
+kubectl logs -n portworx -l app=px-csi-node --tail=100
+
+# Follow logs in real-time
+kubectl logs -n portworx -l app=px-csi-controller -f
+```
+
+## Troubleshooting
+
+### Check iSCSI on Talos Nodes
+```bash
+# List iSCSI sessions
+talosctl -n <node-ip> exec -- iscsiadm -m session
+
+# Discover FlashArray targets
+talosctl -n <node-ip> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
+
+# Check initiator name (must be unique)
+talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
+```
+
+### Check Multipath
+```bash
+# Multipath status
+talosctl -n <node-ip> exec -- multipath -ll
+
+# Reload multipath config
+talosctl -n <node-ip> exec -- systemctl reload multipathd
+
+# Multipath devices
+talosctl -n <node-ip> exec -- ls -l /dev/mapper/
+```
+
+### Verify FlashArray Connectivity
+```bash
+# From PX-CSI pod
+kubectl exec -n portworx -it <px-pod> -- ping <flasharray-ip>
+
+# Test API endpoint
+kubectl exec -n portworx -it <px-pod> -- \
+  curl -k https://<flasharray-mgmt-ip>/api/2.0/arrays
+```
+
+### Check Secret
+```bash
+# Verify secret exists
+kubectl get secret -n portworx px-pure-secret
+
+# View secret content (pure.json)
+kubectl get secret -n portworx px-pure-secret \
+  -o jsonpath='{.data.pure\.json}' | base64 -d | jq .
+
+# Check ExternalSecret status
+kubectl get externalsecret -n portworx px-pure-secret
+kubectl describe externalsecret -n portworx px-pure-secret
+```
+
+### Volume Not Attaching
+```bash
+# Check PVC events
+kubectl describe pvc <pvc-name>
+
+# Check pod events
+kubectl describe pod <pod-name>
+
+# Check PV
+kubectl get pv
+kubectl describe pv <pv-name>
+
+# Check volume attachment
+kubectl get volumeattachment
+```
+
+### Pod Stuck in ContainerCreating
+```bash
+# Check events
+kubectl describe pod <pod-name>
+
+# Check PVC status
+kubectl get pvc -n <namespace>
+
+# Check node where pod is scheduled
+POD_NODE=$(kubectl get pod <pod-name> -o jsonpath='{.spec.nodeName}')
+echo "Pod scheduled on: $POD_NODE"
+
+# Check iSCSI on that node
+talosctl -n $POD_NODE exec -- iscsiadm -m session
+```
+
+## Monitoring
+
+### Prometheus Queries
+```promql
+# Cluster status
+portworx_cluster_status
+
+# Volume capacity
+portworx_volume_capacity_bytes
+
+# Volume usage
+portworx_volume_usage_bytes
+
+# I/O metrics
+rate(portworx_volume_read_bytes[5m])
+rate(portworx_volume_write_bytes[5m])
+```
+
+### List All PVCs Using Pure Storage
+```bash
+# Block storage
+kubectl get pvc --all-namespaces -o json | \
+  jq -r '.items[] | select(.spec.storageClassName == "pure-block") | 
+  "\(.metadata.namespace)/\(.metadata.name) - \(.status.phase)"'
+
+# File storage
+kubectl get pvc --all-namespaces -o json | \
+  jq -r '.items[] | select(.spec.storageClassName == "pure-file") | 
+  "\(.metadata.namespace)/\(.metadata.name) - \(.status.phase)"'
+```
+
+### Storage Usage by Namespace
+```bash
+kubectl get pvc --all-namespaces -o json | \
+  jq -r '.items[] | select(.spec.storageClassName | startswith("pure-")) | 
+  "\(.metadata.namespace)\t\(.spec.resources.requests.storage)"' | \
+  awk '{arr[$1]+=$2} END {for (i in arr) print i, arr[i]}'
+```
+

+# Portworx CSI Driver for Pure Storage FlashArray
+
+GitOps deployment of Portworx CSI driver for Pure Storage FlashArray on Talos Linux in the `fastpass` Kubernetes cluster.
+
+## Overview
+
+Portworx CSI enables Kubernetes to provision and manage storage directly from Pure Storage FlashArray, providing:
+
+- **Block Storage**: High-performance iSCSI volumes for databases and stateful apps
+- **File Storage**: NFS-based shared storage from FlashArray File Services
+- **Dynamic Provisioning**: Automatic volume creation via StorageClasses
+- **Volume Snapshots**: CSI snapshots for backup and restore
+- **Volume Expansion**: Online volume resizing without downtime
+
+## Architecture

+
+## Prerequisites
+
+### 1. FlashArray Configuration
+
+#### Create FlashArray User and API Token
+
+1. **Create a storage admin user:**
+   - Navigate to FlashArray dashboard → **Settings** → **Access** → **Users**
+   - Click **Create User**
+   - Set role to **Storage Admin**
+   - Username: `portworx-csi`
+
+2. **Generate API token:**
+   - Select the user → **Create API Token**
+   - Leave **Expires in** blank for non-expiring token
+   - Copy the token immediately
+
+#### Configure FlashArray for Block Storage (iSCSI)
+
+1. **Verify iSCSI targets are configured:**
+   ```bash
+   # From any Talos node
+   iscsiadm -m discovery -t st -p <flasharray-mgmt-ip>
+   ```
+
+2. **Enable FlashArray network interfaces for iSCSI**
+
+#### Configure FlashArray File Services (Optional - for NFS)
+
+If using FlashArray File Services:
+
+1. **Enable File Services** on FlashArray
+2. **Create a filesystem** for Kubernetes volumes
+3. **Create an NFS policy** with user mapping disabled:
+   - Edit `nfs-simple` policy or create new policy
+   - Disable user mapping to avoid UID/GID issues
+   - Set `no_root_squash` if needed
+
+### 2. 1Password Secret Setup
+
+Create a 1Password item with FlashArray credentials:
+
+**Vault:** `homelab`  
+**Item Name:** `pure-flasharray-fastpass`  
+**Field Name:** `pure.json`  
+**Field Type:** Text  
+**Field Value:**
+```json
+{
+  "FlashArrays": [
+    {
+      "MgmtEndPoint": "flasharray.mk-labs.cloud",
+      "APIToken": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+      "NFSEndPoint": "flasharray-nfs.mk-labs.cloud"
+    }
+  ]
+}
+```
+
+**Notes:**
+- Replace `flasharray.mk-labs.cloud` with your FlashArray management endpoint
+- Replace the API token with the actual token from FlashArray
+- Include `NFSEndPoint` only if using FlashArray File Services
+- For IPv6, enclose IP in brackets: `"[2001:db8::1]"`
+
+### 3. Talos Node Configuration
+
+Apply the following patches to **all worker nodes** in `talos/talhelper/talconfig.yaml`:
+
+```yaml
+nodes:
+  # Add to each worker node definition
+  patches:
+    - |-
+      machine:

+                - bind
+                - rshared
+                - rw
+```
+
+**Apply Talos configuration:**
+```bash
+# From city-hall (talhelper host)
+cd ~/git/homelab/talos/talhelper
+talhelper genconfig
+talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
+
+# Reboot nodes to load kernel modules
+talosctl reboot --nodes <node-ip>
+```
+
+### 4. Verify Talos Prerequisites
+
+After applying Talos configuration and rebooting:
+
+```bash
+# Check iSCSI initiator service
+talosctl -n <node-ip> get service iscsid
+
+# Verify multipath is running
+talosctl -n <node-ip> exec -- multipath -ll
+
+# Check initiator name (must be unique per node)
+talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
+
+# Verify kernel modules loaded
+talosctl -n <node-ip> exec -- lsmod | grep -E "iscsi|dm_multipath"
+
+# Test iSCSI discovery
+talosctl -n <node-ip> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
+```
+
+## Deployment
+
+### 1. Commit and Push to Git
+
+```bash
+cd ~/git/homelab
+git add cluster/platform/portworx-csi/
+git commit -m "Add Portworx CSI driver for Pure FlashArray"
+git push origin main
+```
+
+### 2. Deploy via ArgoCD
+
+The application is configured with `sync-wave: 2`, so it will deploy after External Secrets Operator and 1Password Connect.
+
+**Option A: Auto-sync (recommended)**
+```bash
+# ArgoCD will automatically sync after detecting changes
+# Check status:
+kubectl get application -n argocd portworx-csi
+```
+
+**Option B: Manual sync**
+```bash
+# Sync via CLI
+argocd app sync portworx-csi
+
+# Or sync via UI
+# Navigate to ArgoCD UI → Applications → portworx-csi → Sync
+```
+
+### 3. Verify Deployment
+
+```bash
+# Check ArgoCD application status
+kubectl get application -n argocd portworx-csi
+
+# Check Portworx Operator
+kubectl get deployment -n portworx portworx-operator
+kubectl get pods -n portworx -l app=portworx-operator
+
+# Check StorageCluster status
+kubectl get storagecluster -n portworx px-cluster-fastpass
+kubectl describe storagecluster -n portworx px-cluster-fastpass
+
+# Check PX-CSI pods
+kubectl get pods -n portworx
+
+# Verify secret was created from 1Password
+kubectl get secret -n portworx px-pure-secret
+kubectl get secret -n portworx px-pure-secret -o jsonpath='{.data.pure\.json}' | base64 -d | jq
+
+# Check CSI driver registration
+kubectl get csidrivers
+kubectl get csinode
+
+# Verify StorageClasses
+kubectl get storageclass pure-block pure-file
+```
+
+Expected output:
+```
+NAME                          PROVISIONER         RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION

+```
+
+### Volume Expansion
+
+```bash
+# Edit PVC to increase size
+kubectl patch pvc postgres-data -p '{"spec":{"resources":{"requests":{"storage":"20Gi"}}}}'
+
+# Verify expansion
+kubectl get pvc postgres-data
+```
+

+metadata:
+  name: postgres-backup
+  namespace: default
+spec:
+  volumeSnapshotClassName: px-csi-snapshot-class
+  source:
+    persistentVolumeClaimName: postgres-data
+```
+
+## StorageClasses
+
+### pure-block
+- **Backend:** Pure Storage FlashArray (iSCSI)
+- **Access Mode:** ReadWriteOnce (RWO)
+- **Use Case:** Databases, stateful applications requiring block storage
+- **Features:** High performance, low latency, volume expansion
+- **Filesystem:** ext4
+
+### pure-file
+- **Backend:** Pure Storage FlashArray File Services (NFS)
+- **Access Mode:** ReadWriteMany (RWX)
+- **Use Case:** Shared storage for multi-pod applications
+- **Features:** NFS v4.1, concurrent access, volume expansion
+- **Mount Options:** hard, timeo=600, retrans=3
+
+## Monitoring
+
+Portworx CSI exposes Prometheus metrics:
+
+```bash
+# Check ServiceMonitor (if Prometheus Operator is installed)
+kubectl get servicemonitor -n portworx
+
+# View metrics endpoint
+kubectl get svc -n portworx -l app=portworx-api
+
+# Example metrics:
+# - portworx_volume_usage_bytes
+# - portworx_volume_capacity_bytes
+# - portworx_cluster_status
+```
+
+To enable Prometheus scraping, the `kube-prometheus-stack` will auto-discover the ServiceMonitor.
+
+## Troubleshooting
+
+### Pods stuck in ContainerCreating
+
+```bash
+# Check PVC status
+kubectl get pvc
+kubectl describe pvc <pvc-name>
+
+# Check PV binding
+kubectl get pv
+
+# Check PX-CSI node driver logs
+kubectl logs -n portworx -l app=px-csi-driver --tail=100
+
+# Check iSCSI sessions on node
+talosctl -n <node-ip> exec -- iscsiadm -m session
+```
+
+### Volume not attaching
+
+```bash
+# Check StorageCluster status
+kubectl get storagecluster -n portworx -o yaml
+
+# Check PX-CSI controller logs
+kubectl logs -n portworx -l app=portworx-operator
+
+# Verify FlashArray connectivity
+kubectl exec -n portworx -it <px-pod> -- ping <flasharray-mgmt-ip>
+
+# Check secret is valid
+kubectl get secret -n portworx px-pure-secret -o yaml
+```
+
+### Multipath issues
+
+```bash
+# Check multipath status on node
+talosctl -n <node-ip> exec -- multipath -ll
+
+# Restart multipathd if needed
+talosctl -n <node-ip> exec -- systemctl restart multipathd
+
+# Verify udev rules applied
+talosctl -n <node-ip> exec -- udevadm control --reload-rules
+talosctl -n <node-ip> exec -- udevadm trigger
+```
+
+### FlashArray API errors
+
+```bash
+# Verify API token is valid
+# From a pod with curl:
+curl -k -H "api-token: <token>" https://<flasharray-mgmt-ip>/api/2.0/arrays
+
+# Check PX-CSI can reach FlashArray
+kubectl exec -n portworx -it <px-pod> -- curl -k https://<flasharray-mgmt-ip>
+```
+
+## Rollback
+
+If deployment fails:
+
+```bash
+# Delete ArgoCD application (keeps namespace and CRDs)
+kubectl delete application -n argocd portworx-csi
+
+# Or remove via ArgoCD UI
+
+# Full cleanup (if needed):
+kubectl delete namespace portworx
+kubectl delete crd storageclusters.core.libopenstorage.org
+kubectl delete storageclass pure-block pure-file
+```

+
+## Architecture Decisions
+
+- **Sync Wave 2:** Deployed after External Secrets Operator (wave 1) but before applications
+- **iSCSI Protocol:** Selected for broad compatibility; NVMe-oF can be added later
+- **No Default StorageClass:** Keeps existing `nfs-emporium` as default; apps opt-in to Pure
+- **Telemetry Disabled:** For homelab privacy; can enable for production support
+- **Single FlashArray:** Configuration supports multiple arrays; add to `pure.json` as needed
+
+## Future Enhancements
+
+- [ ] Enable CSI topology for multi-zone deployments
+- [ ] Configure NVMe-oF protocol for lower latency
+- [ ] Set up FlashArray ActiveCluster for HA
+- [ ] Enable Portworx Fusion Controller
+- [ ] Configure VLAN binding for isolated storage traffic
+- [ ] Implement backup/restore workflows with snapshots
+- [ ] Add Grafana dashboards for Portworx metrics

+# Pure FlashArray OpenMetrics Exporter - Deployment Summary
+
+**Deployment Date:** 2026-06-19  
+**Status:** ✅ Successfully Deployed  
+**Namespace:** monitoring  
+**Array:** utilidor.local.mk-labs.cloud (10.1.71.5)
+
+## What Was Deployed
+
+### 1. **Container Deployment**
+- **Image:** `quay.io/purestorage/pure-fa-om-exporter:v1.0.27` (latest stable)
+- **Port:** 9490 (standard exporter port)
+- **Resources:** 50m CPU / 64Mi memory (requests), 200m CPU / 128Mi memory (limits)
+- **Health Checks:** Liveness and readiness probes on / endpoint
+- **Security:** Running as non-root user (65534)
+
+### 2. **Secret Configuration**
+- **Secret Name:** `pure-fa-exporter-token`
+- **Contains:** tokens.yaml with FlashArray endpoint and API token
+- **Array ID:** utilidor
+- **Endpoint:** utilidor.local.mk-labs.cloud
+- **API Token:** 6157dea0-4c0d-b14b-6e6a-453aa649355d (jarvis readonly user)
+
+### 3. **Service**
+- **Type:** ClusterIP (east/west traffic only)
+- **Port:** 9490
+- **Selector:** app.kubernetes.io/name=pure-fa-exporter
+
+### 4. **ServiceMonitor**
+- **Scrape Interval:** 60s (storage metrics low frequency)
+- **Scrape Timeout:** 30s
+- **Path:** /metrics?endpoint=utilidor
+- **Label Selector:** release=monitoring (for kube-prometheus-stack)
+- **Relabeling:** Adds 'array' label from endpoint parameter
+
+### 5. **ArgoCD Application**
+- **Wave:** 3 (monitoring infrastructure)
+- **Sync Policy:** Automated with prune and self-heal
+- **Source:** cluster/platform/pure-exporter/
+- **Health:** ✅ Healthy
+- **Sync Status:** ✅ Synced
+
+## Verification Results
+
+### ✅ Pod Status
+```
+NAME                               READY   STATUS    RESTARTS   AGE
+pure-fa-exporter-7d45dcfb7-9rxj2   1/1     Running   0          21s

+pure-fa-exporter   ClusterIP   10.111.204.251   <none>        9490/TCP   29s
+```
+
+### ✅ Metrics Available
+Successfully scraped FlashArray metrics including:
+- `purefa_info` - System information (Purity//FA 6.5.13)
+- `purefa_alerts_open` - Alert events
+- `purefa_array_performance_*` - Performance metrics (IOPS, bandwidth, latency)
+- `purefa_array_space_*` - Capacity metrics
+- `purefa_volume_*` - Volume metrics
+- `purefa_host_*` - Host metrics
+- And many more...
+
+Sample output:
+```
+purefa_info{array_name="utilidor",os="Purity//FA",subscription_type="FlashArray",system_id="b78a62d3-57fc-45ab-b73f-6203fb30f28d",version="6.5.13"} 1
+```
+
+## Files Created
+
+All manifests committed to homelab repo:
+
+1. **application.yaml** - ArgoCD Application definition (wave 3)
+2. **deployment.yaml** - Exporter deployment with health checks and resource limits
+3. **secret.yaml** - FlashArray API credentials (tokens.yaml format)
+4. **service.yaml** - ClusterIP service exposing /metrics
+5. **servicemonitor.yaml** - Prometheus Operator integration
+
+**Git Commit:** cb5ffc1 - "Add Pure FlashArray OpenMetrics exporter to monitoring namespace"
+
+## Next Steps for JARVIS
+
+1. **Verify Prometheus Scraping**
+   - Check Prometheus UI → Status → Targets
+   - Look for `serviceMonitor/monitoring/pure-fa-exporter/0` target
+   - Should show state: UP
+
+2. **Test Metrics in Prometheus**
+   - Navigate to Prometheus UI → Graph
+   - Query: `purefa_info` - Should return array information
+   - Query: `purefa_array_space_bytes{space="capacity"}` - Total capacity
+   - Query: `purefa_array_performance_throughput_iops` - IOPS metrics
+
+3. **Grafana Dashboard (Optional)**
+   - The Pure Storage community provides Grafana dashboards
+   - Reference: https://github.com/PureStorage-OpenConnect/pure-fa-openmetrics-exporter/tree/master/extra/grafana
+   - Can import dashboard JSON for fleet-wide overview
+
+## Configuration Notes
+
+### Multi-Target Exporter Pattern
+The exporter follows Prometheus multi-target pattern:
+- Single exporter instance can scrape multiple arrays
+- Array selection via `?endpoint=<array_id>` query parameter
+- Array credentials in tokens.yaml (array_id → endpoint + api_token mapping)
+
+### Scrape Frequency
+- **Current:** 60s interval
+- **Rationale:** Storage metrics are relatively static, high frequency unnecessary
+- **Adjustable:** Modify servicemonitor.yaml if faster updates needed
+
+### Security Context
+- Runs as non-root user (UID 65534)
+- Read-only token mount
+- No elevated privileges required
+
+## Troubleshooting
+
+If metrics are not appearing in Prometheus:
+
+1. **Check ServiceMonitor Selection**
+   ```bash
+   kubectl get servicemonitor -n monitoring pure-fa-exporter -o yaml
+   ```
+   Ensure `release: monitoring` label exists for prometheus-operator selector
+
+2. **Verify Exporter Logs**
+   ```bash
+   kubectl logs -n monitoring -l app.kubernetes.io/name=pure-fa-exporter
+   ```
+
+3. **Test Endpoint Directly**
+   ```bash
+   kubectl run curl-test --image=curlimages/curl:latest --rm -i --restart=Never -n monitoring -- \
+     curl -s http://pure-fa-exporter:9490/metrics?endpoint=utilidor | head
+   ```
+
+4. **Check Prometheus Operator Logs**
+   ```bash
+   kubectl logs -n monitoring -l app.kubernetes.io/name=prometheus-operator
+   ```
+
+## References
+
+- **Official Repo:** https://github.com/PureStorage-OpenConnect/pure-fa-openmetrics-exporter
+- **Metrics Specification:** See repo for full purefa_* metric namespace documentation
+- **Deployment Pattern:** Based on portworx-csi GitOps structure
+- **ServiceMonitor Pattern:** Based on kube-prometheus-stack conventions
+
+---
+
+**Deployment completed successfully.** Prometheus should begin scraping FlashArray metrics within 60 seconds.

+
+## System Extensions
+
+System extensions in Talos v1.13+ are baked into custom boot images via **schematics** and the Talos Image Factory, not loaded at runtime.
+
+### Adding Extensions
+
+Edit `talhelper/talconfig.yaml` and add extensions to the worker or control plane section:
+
+```yaml
+# ─── Worker patches ──────────────────────────────────────────────────────────
+worker:
+  schematic:
+    customization:
+      systemExtensions:
+        officialExtensions:
+          - siderolabs/iscsi-tools
+          - siderolabs/util-linux-tools
+  patches:
+    - |-
+      machine:
+        kernel:
+          modules:
+            - name: iscsi_tcp
+            - name: dm_multipath
+```
+
+**Common extensions:**
+- `siderolabs/iscsi-tools` - iSCSI initiator utilities
+- `siderolabs/util-linux-tools` - Multipath and storage utilities
+- `siderolabs/qemu-guest-agent` - Proxmox/QEMU guest agent
+- `siderolabs/nvidia-container-toolkit` - NVIDIA GPU support
+
+**Browse available extensions:**
+```bash
+curl -s https://factory.talos.dev/schematics | jq '.extensions[] | .name'
+```
+
+### Applying Extensions
+
+Extensions require an **upgrade** (new OS image), not `apply-config`:
+
+```bash
+cd /opt/git/homelab/talos/talhelper
+
+# 1. Generate configs with schematic
+talhelper genconfig
+
+# 2. Generate upgrade commands
+talhelper gencommand upgrade --extra-flags="--preserve"
+
+# 3. Copy the output commands and run them one node at a time
+# Example output:
+# talosctl upgrade --nodes 10.1.71.69 --image factory.talos.dev/installer/<schematic>:v1.13.2 --preserve
+```
+
+**Manual rolling upgrade for workers:**
+
+```bash
+# Worker 1
+talosctl upgrade --nodes 10.1.71.69 \
+  --image factory.talos.dev/installer/<schematic-id>:v1.13.2 \
+  --preserve
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+sleep 30
+
+# Worker 2
+talosctl upgrade --nodes 10.1.71.70 \
+  --image factory.talos.dev/installer/<schematic-id>:v1.13.2 \
+  --preserve
+kubectl wait --for=condition=Ready node/haunted-mansion --timeout=10m
+sleep 30
+
+# Worker 3
+talosctl upgrade --nodes 10.1.71.71 \
+  --image factory.talos.dev/installer/<schematic-id>:v1.13.2 \
+  --preserve
+kubectl wait --for=condition=Ready node/peter-pans-flight --timeout=10m
+```
+
+**Verify extensions:**
+
+```bash
+# List installed extensions
+talosctl -n 10.1.71.69 get extensions
+
+# Verify specific modules
+talosctl -n 10.1.71.69 read /proc/modules | grep iscsi
+```
+
+---
+
+## Upgrading Talos Versions
+
+### Pre-Upgrade Checklist
+
+1. **Review release notes:** https://github.com/siderolabs/talos/releases
+2. **Check Kubernetes compatibility:** Ensure your K8s version is supported
+3. **Backup etcd:** Control plane data
+4. **Take VM snapshots:** If running on Proxmox/vSphere
+5. **Check extension compatibility:** Ensure extensions exist for new Talos version
+
+### Upgrade Process
+
+#### Step 1: Update talconfig.yaml
+
+```yaml
+clusterName: fastpass
+talosVersion: v1.14.0  # <- Update this
+kubernetesVersion: v1.32.3
+```
+
+#### Step 2: Regenerate Configs
+
+```bash
+cd /opt/git/homelab/talos/talhelper
+talhelper genconfig
+```
+
+#### Step 3: Upgrade Control Plane (One at a Time)
+
+```bash
+# Generate upgrade commands
+talhelper gencommand upgrade --extra-flags="--preserve"
+
+# Control plane node 1
+talosctl upgrade --nodes 10.1.71.66 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/space-mountain --timeout=10m
+sleep 60
+
+# Control plane node 2
+talosctl upgrade --nodes 10.1.71.67 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/big-thunder-mountain --timeout=10m
+sleep 60
+
+# Control plane node 3
+talosctl upgrade --nodes 10.1.71.68 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/splash-mountain --timeout=10m
+sleep 60
+```
+
+**IMPORTANT:** Always upgrade control plane nodes **one at a time** with sufficient wait between each. Etcd requires quorum (2 of 3 nodes) to remain operational.
+
+#### Step 4: Upgrade Workers (Rolling)
+
+After all control plane nodes are upgraded:
+
+```bash
+# Worker nodes (can be faster since no etcd)
+talosctl upgrade --nodes 10.1.71.69 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+sleep 30
+
+talosctl upgrade --nodes 10.1.71.70 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/haunted-mansion --timeout=10m
+sleep 30
+
+talosctl upgrade --nodes 10.1.71.71 \
+  --image factory.talos.dev/installer/<schematic>:v1.14.0 \
+  --preserve
+kubectl wait --for=condition=Ready node/peter-pans-flight --timeout=10m
+```
+
+#### Step 5: Verify Cluster
+
+```bash
+# Check all nodes
+kubectl get nodes -o wide
+
+# Verify Talos version
+talosctl -n 10.1.71.66,10.1.71.67,10.1.71.68 version
+
+# Check cluster health
+kubectl get pods -A | grep -v Running
+talosctl -n 10.1.71.66 service kubelet status
+```
+
+---
+
+## Rolling Upgrades (Workers)
+
+### Automated Rolling Upgrade Script
+
+```bash
+#!/bin/bash
+# rolling-upgrade-workers.sh
+
+set -e
+
+IMAGE="$1"
+if [ -z "$IMAGE" ]; then
+  echo "Usage: $0 <image-url>"
+  echo "Example: $0 factory.talos.dev/installer/abc123:v1.14.0"
+  exit 1
+fi
+
+declare -A WORKERS=(
+  ["jungle-cruise"]="10.1.71.69"
+  ["haunted-mansion"]="10.1.71.70"
+  ["peter-pans-flight"]="10.1.71.71"
+)
+
+for worker in "${!WORKERS[@]}"; do
+  ip="${WORKERS[$worker]}"
+  echo "=========================================="
+  echo "Upgrading $worker ($ip)..."
+  echo "=========================================="
+  
+  talosctl upgrade --nodes ${ip} --image ${IMAGE} --preserve
+  
+  echo "Waiting for $worker to be Ready..."
+  kubectl wait --for=condition=Ready node/${worker} --timeout=10m
+  
+  echo "$worker upgrade complete. Sleeping 30s before next node..."
+  sleep 30
+done
+
+echo "=========================================="
+echo "All workers upgraded successfully!"
+echo "=========================================="
+```
+
+**Usage:**
+
+```bash
+cd /opt/git/homelab/talos/talhelper
+chmod +x rolling-upgrade-workers.sh
+
+# Get the image URL from talhelper
+IMAGE=$(grep "image:" clusterconfig/fastpass-jungle-cruise.yaml | head -1 | awk '{print $2}')
+
+# Run the rolling upgrade
+./rolling-upgrade-workers.sh "$IMAGE"
+```
+
+---
+
+## Upgrading Kubernetes Version
+
+Talos manages Kubernetes. To upgrade K8s:
+
+### Step 1: Update talconfig.yaml
+
+```yaml
+clusterName: fastpass
+talosVersion: v1.14.0
+kubernetesVersion: v1.33.0  # <- Update this
+```
+
+### Step 2: Regenerate and Apply
+
+```bash
+cd /opt/git/homelab/talos/talhelper
+talhelper genconfig
+
+# Apply config changes (does NOT require node reboot)
+talosctl -n 10.1.71.66,10.1.71.67,10.1.71.68 upgrade-k8s --to v1.33.0
+```
+
+**The `upgrade-k8s` command:**
+- Upgrades control plane components (apiserver, scheduler, controller-manager) first
+- Then upgrades kubelet on all nodes
+- Does NOT reboot nodes (in-place upgrade)
+- Automatic rolling update
+
+**Verify:**
+
+```bash
+kubectl get nodes -o wide
+# Check both Talos version and Kubernetes version columns
+```
+
+---
+
+## Troubleshooting
+
+### Extension Not Found Error
+
+**Error:** `module not found` when loading kernel modules
+
+**Cause:** Module isn't in the base Talos image or extension wasn't applied
+
+**Fix:**
+1. Check if extension exists: `curl -s https://factory.talos.dev/schematics | jq '.extensions[] | select(.name | contains("iscsi"))'`
+2. Verify schematic in config: `grep -A10 "schematic:" talhelper/talconfig.yaml`
+3. Confirm extension is loaded: `talosctl -n <node-ip> get extensions`
+
+### Upgrade Fails with "invalid reference format"
+
+**Error:** `failed to parse image reference`
+
+**Cause:** Incorrect image URL format or missing schematic
+
+**Fix:**
+1. Manually check generated image URL: `grep "image:" clusterconfig/fastpass-<node>.yaml`
+2. Use talhelper's upgrade command generator: `talhelper gencommand upgrade`
+3. Ensure format is: `factory.talos.dev/installer/<schematic-id>:<version>`
+
+### Node Stuck in "NotReady" After Upgrade
+
+**Symptoms:** Node shows NotReady for >5 minutes post-upgrade
+
+**Debug:**
+```bash
+# Check node status
+kubectl describe node <node-name>
+
+# Check Talos services
+talosctl -n <node-ip> service kubelet status
+talosctl -n <node-ip> service containerd status
+
+# Check logs
+talosctl -n <node-ip> logs kubelet
+talosctl -n <node-ip> dmesg | tail -50
+```
+
+**Common causes:**
+- Network policy blocking CNI (Cilium)
+- iSCSI/storage mounts failing
+- Kernel module load failure
+- Certificate rotation issues
+
+### Control Plane Quorum Lost
+
+**Symptoms:** `etcdserver: no leader` errors, apiserver unavailable
+
+**Prevention:**
+- **NEVER** upgrade more than 1 control plane node simultaneously
+- Always wait for full Ready status + 60s between CP upgrades
+- Verify etcd health before proceeding: `talosctl -n 10.1.71.66 service etcd status`
+
+**Recovery:**
+If quorum is lost (2 of 3 nodes down):
+```bash
+# Wait for at least 2 nodes to come back online
+# Check etcd cluster status
+talosctl -n 10.1.71.66,10.1.71.67,10.1.71.68 service etcd status
+
+# If completely broken, may require etcd disaster recovery
+# See: https://www.talos.dev/v1.13/advanced/disaster-recovery/
+```
+
+---
+
+## Quick Reference
+
+### Check Current Versions
+
+```bash
+# Talos version on all nodes
+talosctl -n 10.1.71.66,10.1.71.67,10.1.71.68,10.1.71.69,10.1.71.70,10.1.71.71 version
+
+# Kubernetes version
+kubectl version
+
+# Installed extensions
+talosctl -n 10.1.71.69 get extensions
+```
+
+### Safe Upgrade Order
+
+1. ✅ Control plane node 1 → wait → verify
+2. ✅ Control plane node 2 → wait → verify
+3. ✅ Control plane node 3 → wait → verify
+4. ✅ Worker nodes (can be parallel or rolling)
+
+### Config Changes vs. OS Upgrades
+
+| Change Type | Command | Reboot Required? |
+|-------------|---------|------------------|
+| Network config, sysctls, files | `talosctl apply-config --mode=reboot` | Yes |
+| Kubernetes version | `talosctl upgrade-k8s` | No |
+| Talos version | `talosctl upgrade` | Yes |
+| System extensions | `talosctl upgrade` | Yes |

+# Talos iSCSI Configuration Fix - Deployment Summary
+
+**Date:** 2026-06-20  
+**Cluster:** fastpass  
+**Talos Version:** v1.13.2  
+**Purpose:** Fix iSCSI configuration for Portworx CSI / Pure Storage FlashArray integration
+
+## Executive Summary
+
+The initial iSCSI configuration (commit f370213) caused worker nodes to fail boot with error:
+```
+writeUserFiles failed, rebooting in 35 minutes
+```
+
+This fix resolves the boot failure by:
+1. Removing problematic `/etc/iscsi` bind mount
+2. Adding explicit `nodeIP` configuration for dual-NIC workers
+3. Moving multipath configuration to post-boot DaemonSet
+4. Ensuring proper file operation semantics
+
+## Changes Made
+
+### 1. Updated talconfig.yaml
+
+**Location:** `~/git/homelab/talos/talhelper/talconfig.yaml`
+
+**Changes:**
+- ✅ Removed `/etc/iscsi` mount (iscsi-tools extension manages it)
+- ✅ Added `kubelet.nodeIP.validSubnets: [10.1.71.0/24]` for dual-NIC handling
+- ✅ Added `rw` option to `/var/lib/iscsi` mount
+- ✅ Removed `files` section with `/etc/multipath.conf` (moved to DaemonSet)
+- ✅ Kept kernel modules: iscsi_tcp, dm_multipath, dm_round_robin
+- ✅ Kept ARP sysctls for dual-NIC environment
+
+**Worker Patch (lines 115-156):**

+          net.ipv4.conf.all.arp_announce: "2"
+          net.ipv4.conf.all.arp_ignore: "1"
+```
+
+### 2. Created iscsi-multipath-init.yaml
+
+**Location:** `~/git/homelab/talos/talhelper/iscsi-multipath-init.yaml`
+
+**Purpose:** DaemonSet that configures multipath.conf post-boot
+
+**Features:**
+- Runs on all worker nodes (nodeSelector: node-role.kubernetes.io/worker)
+- InitContainer writes `/etc/multipath.conf` with Pure Storage settings
+- Configures multipath blacklist for Portworx devices (pxd*)
+- Pause container keeps pod running to indicate configuration is applied
+- Privileged container with hostNetwork and hostPID for host access
+
+**Deployment:**
+```bash
+kubectl apply -f iscsi-multipath-init.yaml
+```
+
+### 3. Created apply-iscsi-fix.sh
+
+**Location:** `~/git/homelab/talos/talhelper/apply-iscsi-fix.sh`
+
+**Purpose:** Automated script to apply configuration to all worker nodes
+
+**Features:**
+- Regenerates Talos config with talhelper
+- Applies config to workers sequentially (one at a time)
+- Waits for each node to reboot and become Ready
+- Verifies iSCSI functionality after each update
+- Deploys multipath DaemonSet
+- Comprehensive error handling and status reporting
+
+**Usage:**
+```bash
+./apply-iscsi-fix.sh           # Apply changes
+./apply-iscsi-fix.sh --dry-run # Preview without applying
+```
+
+### 4. Created verify-iscsi.sh
+
+**Location:** `~/git/homelab/talos/talhelper/verify-iscsi.sh`
+
+**Purpose:** Verification script to check iSCSI configuration
+
+**Checks:**
+- Node Ready status
+- Node IP (should be 10.1.71.x, not 10.1.75.x)
+- System extensions installed
+- Kernel modules loaded
+- iscsid service status
+- Initiator name configured
+- /var/lib/iscsi accessibility
+- Multipath configuration
+- Network connectivity on ens19
+- Optional: FlashArray connectivity and discovery
+
+**Usage:**
+```bash
+./verify-iscsi.sh                    # Basic verification
+./verify-iscsi.sh 10.1.75.100        # With FlashArray connectivity test
+```
+
+### 5. Created ISCSI_CONFIG_FIX.md
+
+**Location:** `~/git/homelab/talos/talhelper/ISCSI_CONFIG_FIX.md`
+
+**Purpose:** Comprehensive documentation explaining:
+- Root cause of the writeUserFiles failure
+- Detailed explanation of each fix
+- Two configuration options (minimal and advanced)
+- Step-by-step application procedure
+- Verification commands
+- Portworx-specific considerations
+- Troubleshooting guide
+
+## Root Cause Analysis
+
+### Why the Boot Failed
+
+1. **`/etc/iscsi` mount conflict:**
+   - `/etc/iscsi` is part of Talos read-only system partition
+   - iscsi-tools extension manages this directory automatically
+   - Explicit bind mount caused filesystem conflict during boot
+   - Talos couldn't write initiator configuration → boot failure
+
+2. **`/etc/multipath.conf` timing issue:**
+   - `op: create` writes files during early boot
+   - Target filesystem may not be writable yet
+   - Talos has strict boot sequence for security
+   - File writing at wrong time triggers writeUserFiles error
+
+3. **Dual NIC ambiguity:**
+   - Not directly causing boot failure
+   - But kubelet could select wrong interface (10.1.75.x instead of 10.1.71.x)
+   - Would cause pod networking issues
+   - Fixed with explicit nodeIP.validSubnets
+
+## Deployment Plan
+
+### Prerequisites
+
+- [x] Configuration files reviewed
+- [ ] Current worker nodes are healthy
+- [ ] Cluster has capacity to lose one worker at a time
+- [ ] Backup of current talconfig.yaml committed to git
+- [ ] Access to talosctl and kubectl
+- [ ] Access to Kubernetes cluster
+
+### Execution Steps
+
+#### Phase 1: Preparation
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# Review changes
+git diff HEAD talconfig.yaml
+
+# Dry run to preview
+./apply-iscsi-fix.sh --dry-run
+```
+
+#### Phase 2: Apply Configuration
+```bash
+# Apply to all worker nodes
+./apply-iscsi-fix.sh
+
+# This will:
+# 1. Regenerate configs
+# 2. Apply to jungle-cruise (wait for Ready)
+# 3. Apply to haunted-mansion (wait for Ready)
+# 4. Apply to peter-pans-flight (wait for Ready)
+# 5. Deploy multipath DaemonSet
+# 6. Run verification
+```
+
+Expected duration: ~20-30 minutes (3 nodes × 5-10 min reboot each)
+
+#### Phase 3: Verification
+```bash
+# Comprehensive verification (replace with FlashArray IP)
+./verify-iscsi.sh 10.1.75.100
+
+# Check node IPs
+kubectl get nodes -o wide
+
+# Expected: All workers show 10.1.71.x as INTERNAL-IP
+
+# Check multipath DaemonSet
+kubectl get daemonset -n kube-system iscsi-multipath-init
+kubectl get pods -n kube-system -l app=iscsi-multipath-init -o wide
+
+# Manual verification on one node
+talosctl -n 10.1.71.69 read /etc/multipath.conf
+talosctl -n 10.1.71.69 exec -- multipath -ll
+```
+
+#### Phase 4: Portworx Integration
+```bash
+# After verification, proceed with Portworx deployment
+# (if not already deployed)
+
+# Test iSCSI discovery from a worker
+talosctl -n 10.1.71.69 exec -- \
+  iscsiadm -m discovery -t st -p <flasharray-iscsi-ip>
+
+# Expected: List of iSCSI targets from FlashArray
+```
+
+### Rollback Plan
+
+If issues occur:
+
+```bash
+# Revert talconfig.yaml to previous version
+cd ~/git/homelab/talos/talhelper
+git checkout HEAD^ -- talconfig.yaml
+
+# Regenerate and apply
+talhelper genconfig
+talosctl apply-config --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+
+# Wait for node Ready
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+
+# Repeat for other workers
+```
+
+## Testing Checklist
+
+After deployment:
+
+- [ ] All worker nodes show Ready status
+- [ ] Node IPs are 10.1.71.x (not 10.1.75.x)
+- [ ] iscsi-tools extension loaded on all workers
+- [ ] Kernel modules (iscsi_tcp, dm_multipath, dm_round_robin) loaded
+- [ ] iscsid service running or ready to start
+- [ ] /var/lib/iscsi directory accessible

+# Talos iSCSI Configuration Fix - Implementation Report
+
+**Date:** 2026-06-20  
+**Task:** Configure Talos Linux worker nodes for Portworx CSI iSCSI storage integration  
+**Status:** ✅ Configuration Fixed - Ready for Deployment  
+**Cluster:** fastpass (Talos v1.13.2)
+
+---
+
+## Executive Summary
+
+Successfully diagnosed and fixed the Talos worker node iSCSI configuration that was causing boot failures. The original configuration (commit f370213) attempted to mount `/etc/iscsi` and write `/etc/multipath.conf` during boot, triggering a `writeUserFiles failed` error.

+The fix removes problematic early-boot file operations, adds explicit dual-NIC handling, and moves multipath configuration to a post-boot DaemonSet approach.
+
+## Problem Analysis
+
+### Root Cause
+
+The boot failure was caused by three issues:
+
+1. **`/etc/iscsi` bind mount conflict**
+   - `/etc/iscsi` is managed by the iscsi-tools system extension
+   - Attempting to bind-mount it caused a filesystem conflict
+   - Talos couldn't write initiator configuration during boot
+   - Result: `writeUserFiles failed, rebooting in 35 minutes`
+
+2. **Early boot file writing**
+   - `op: create` for `/etc/multipath.conf` occurred during early boot
+   - Target filesystem not yet writable at that stage
+   - Violated Talos's strict boot sequence security model
+
+3. **Dual-NIC ambiguity**
+   - Workers have ens18 (10.1.71.x) and ens19 (10.1.75.x)
+   - Without explicit nodeIP, kubelet could select wrong interface
+   - Would cause pod networking issues
+
+### Failed Configuration (Commit f370213)
+
+```yaml

+  patches:
+    - machine:
+        kubelet:

+
+### Key Changes
+
+| Component | Change | Reason |
+|-----------|--------|--------|
+| `/etc/iscsi` | **Removed mount** | iscsi-tools extension manages it automatically |
+| `/var/lib/iscsi` | **Added `rw` option** | Ensure iSCSI session data is writable |
+| `multipath.conf` | **Removed from files** | Moved to DaemonSet for post-boot configuration |
+| `nodeIP` | **Added validSubnets** | Force kubelet to bind to 10.1.71.0/24 (ens18) |
+
+### Post-Boot Multipath Configuration
+
+Created DaemonSet (`iscsi-multipath-init.yaml`) that:
+- Runs on all worker nodes after boot
+- Writes `/etc/multipath.conf` when filesystem is fully writable
+- Configures Pure Storage FlashArray settings
+- Blacklists Portworx virtual devices (pxd*)
+- Reloads multipathd configuration

+# 3. Verify
+./verify-iscsi.sh <flasharray-iscsi-ip>
+```
+
+**Expected Duration:** 20-30 minutes
+
+### What the Script Does
+
+1. **Regenerates** Talos configs with talhelper
+2. **Applies** to jungle-cruise (10.1.71.69)
+3. **Waits** for node to reboot and become Ready
+4. **Verifies** iSCSI functionality on jungle-cruise

+
+After deployment, all of the following should be true:
+
+✅ All worker nodes show `Ready` status  
+✅ Node internal IPs are `10.1.71.x` (not `10.1.75.x`)  
+✅ `iscsi-tools` extension loaded on all workers  
+✅ Kernel modules loaded: `iscsi_tcp`, `dm_multipath`, `dm_round_robin`  
+✅ `iscsid` service running or ready to start  
+✅ `/var/lib/iscsi` directory accessible  
+✅ Unique initiator name on each node  
+✅ `/etc/multipath.conf` exists with Pure Storage configuration  
+✅ `ens19` interface up with `10.1.75.x` IP address  
+✅ Multipath DaemonSet running on all workers  
+✅ iSCSI discovery to FlashArray succeeds  
+✅ No boot errors in `dmesg`  
+✅ No `writeUserFiles` errors  
+
+### Verification Commands
+
+```bash
+# Quick status check
+kubectl get nodes -o wide
+kubectl get pods -n kube-system -l app=iscsi-multipath-init
+
+# Comprehensive verification

+
+## Testing Recommendations
+
+### Phase 1: Single Node Test (Recommended)
+
+Before applying to all workers, test on one node:
+
+```bash
+# Edit apply-iscsi-fix.sh to only process jungle-cruise
+# Or manually apply:
+
+talhelper genconfig
+talosctl apply-config \
+  --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+
+# Wait and verify
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+./verify-iscsi.sh <flasharray-ip>
+
+# If successful, proceed with other nodes
+```
+
+### Phase 2: Full Deployment
+
+Once verified on one node, proceed with full deployment:
+
+```bash
+./apply-iscsi-fix.sh
+```
+
+### Phase 3: Portworx Integration
+
+After all workers are updated:
+
+```bash
+# Deploy Portworx CSI (if not already deployed)
+cd ~/git/homelab/cluster/platform/portworx-csi
+# Follow README.md
+
+# Test PVC creation
+kubectl apply -f - <<EOF
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: test-pure-block
+spec:
+  accessModes: [ReadWriteOnce]
+  storageClassName: pure-block
+  resources:
+    requests:
+      storage: 10Gi
+EOF
+
+# Monitor
+kubectl get pvc test-pure-block -w
+```
+
+## Rollback Procedure
+
+If issues occur:
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# Revert talconfig.yaml to previous version
+git checkout HEAD~1 -- talconfig.yaml
+
+# Regenerate configs
+talhelper genconfig
+
+# Apply to affected nodes
+talosctl apply-config \
+  --file clusterconfig/fastpass-<node>.yaml \
+  --nodes <node-ip>
+
+# Wait for Ready
+kubectl wait --for=condition=Ready node/<node> --timeout=10m
+```
+
+## Git Workflow
+

+## Known Limitations
+
+1. **No automatic rollback** - If deployment fails, manual rollback required
+2. **Sequential deployment** - Workers updated one at a time (not parallel)
+3. **FlashArray required for full testing** - Some verification steps need storage connectivity
+4. **Talos-specific** - Solution only applicable to Talos Linux (not other distros)
+
+## Future Enhancements
+
+- [ ] Add parallel node updates (with proper cluster capacity checks)
+- [ ] Integrate with CI/CD for automated testing
+- [ ] Add Prometheus monitoring for iSCSI session health
+- [ ] Create Grafana dashboard for multipath statistics
+- [ ] Automate FlashArray discovery and connectivity testing
+- [ ] Add support for multiple FlashArray backends

+# Talos iSCSI Configuration Fix for Portworx CSI
+
+## Root Cause Analysis
+
+The `writeUserFiles failed` error occurred because:
+
+1. **`/etc/iscsi` bind mount issue**: Talos creates `/var/lib/iscsi` for the iSCSI initiator data, but `/etc/iscsi` is part of the read-only system partition. The iscsi-tools extension manages initiator configuration automatically; explicitly mounting `/etc/iscsi` is unnecessary and causes boot failures.
+
+2. **`/etc/multipath.conf` timing**: Writing files with `op: create` during early boot can fail if the target filesystem is not yet writable. Talos prefers system extensions to handle such configuration.
+
+3. **Dual NIC ambiguity**: With two NICs (ens18 for management, ens19 for iSCSI), kubelet needs explicit `nodeIP` configuration to avoid selecting the wrong interface.
+
+4. **Multipath daemon initialization**: The multipath.conf file needs to exist before multipathd starts, but Talos boot sequence is strict about when files can be written.
+
+## Fixed Configuration
+
+### Option 1: Minimal Safe Configuration (Recommended)
+
+This configuration enables iSCSI without breaking boot:
+
+```yaml
+worker:
+  schematic:
+    customization:
+      systemExtensions:
+        officialExtensions:
+          - siderolabs/qemu-guest-agent
+          - siderolabs/util-linux-tools
+          - siderolabs/iscsi-tools
+
+  patches:
+    - |-
+      machine:
+        # Load required kernel modules for iSCSI and multipath
+        kernel:
+          modules:
+            - name: iscsi_tcp
+            - name: dm_multipath
+            - name: dm_round_robin
+
+        # CRITICAL: Explicitly set nodeIP to primary network to avoid dual-NIC issues
+        kubelet:
+          nodeIP:
+            validSubnets:
+              - 10.1.71.0/24
+          
+          # Only mount /var/lib/iscsi (NOT /etc/iscsi)
+          # The iscsi-tools extension manages /etc/iscsi automatically
+          extraMounts:
+            - destination: /var/lib/iscsi
+              type: bind
+              source: /var/lib/iscsi
+              options:
+                - bind
+                - rshared
+                - rw
+
+        # ARP tuning for dual-NIC setup
+        sysctls:
+          net.ipv4.conf.all.arp_announce: "2"
+          net.ipv4.conf.all.arp_ignore: "1"
+```
+
+**Why this works:**
+- ✅ No `/etc/iscsi` mount (extension handles it)
+- ✅ Only `/var/lib/iscsi` mounted (where iSCSI session data lives)
+- ✅ Explicit `nodeIP` to avoid kubelet binding to iSCSI network
+- ✅ No files written during boot (avoids writeUserFiles error)
+- ✅ Pure Storage multipath can be configured post-boot via DaemonSet
+
+### Option 2: With Multipath Configuration (Advanced)
+
+If you need multipath.conf at boot time (only needed if you have EXISTING iSCSI volumes before Portworx deploys):
+
+```yaml
+worker:
+  schematic:
+    customization:
+      systemExtensions:
+        officialExtensions:
+          - siderolabs/qemu-guest-agent
+          - siderolabs/util-linux-tools
+          - siderolabs/iscsi-tools
+
+  patches:
+    - |-
+      machine:
+        kernel:
+          modules:
+            - name: iscsi_tcp
+            - name: dm_multipath
+            - name: dm_round_robin
+
+        kubelet:
+          nodeIP:
+            validSubnets:
+              - 10.1.71.0/24
+          extraMounts:
+            - destination: /var/lib/iscsi
+              type: bind
+              source: /var/lib/iscsi
+              options:
+                - bind
+                - rshared
+                - rw
+
+        sysctls:
+          net.ipv4.conf.all.arp_announce: "2"
+          net.ipv4.conf.all.arp_ignore: "1"
+        
+        # Use 'op: overwrite' instead of 'create' to avoid boot-time failures
+        # Place in /var/ which is writable, then link if needed
+        files:
+          - content: |
+              defaults {
+                  polling_interval 10
+                  find_multipaths yes
+                  user_friendly_names no
+              }
+              devices {
+                  device {
+                      vendor "PURE"
+                      product "FlashArray"
+                      path_selector "service-time 0"
+                      path_grouping_policy group_by_prio
+                      prio alua
+                      path_checker tur
+                      fast_io_fail_tmo 10
+                      user_friendly_names no
+                      no_path_retry 0
+                      hardware_handler "1 alua"
+                      dev_loss_tmo 600
+                      failback immediate
+                  }
+              }
+              # Blacklist Portworx virtual devices
+              blacklist {
+                  devnode "^pxd[0-9]*"
+              }
+            path: /var/etc/multipath.conf
+            permissions: 0644
+            op: overwrite
+```
+
+**Note:** With this approach, you'd need a startup service or init container to symlink `/var/etc/multipath.conf` to `/etc/multipath.conf`. However, **Option 1 is safer and sufficient** for Portworx, which can configure multipath dynamically.
+
+## Recommended Approach: Option 1 + Portworx DaemonSet Init
+
+**Use Option 1 (minimal config) and let Portworx handle multipath configuration via DaemonSet init containers.**
+
+Portworx CSI driver can deploy an init DaemonSet that:
+1. Configures multipath.conf post-boot
+2. Starts multipathd service
+3. Handles Pure Storage-specific tuning
+
+This is safer because:
+- ✅ No boot-time file writing
+- ✅ Configuration happens after filesystem is fully writable
+- ✅ Can be updated without rebooting nodes
+- ✅ Portworx team maintains the optimal multipath settings
+
+## Application Steps
+
+### 1. Apply the Fixed Configuration
+
+```bash
+cd ~/git/homelab/talos/talhelper
+```
+
+Edit `talconfig.yaml` and replace the worker section with **Option 1** above.
+
+### 2. Regenerate Talos Configuration
+
+```bash
+talhelper genconfig
+```
+
+### 3. Apply to Worker Nodes (One at a Time)
+
+```bash
+# jungle-cruise
+talosctl apply-config --file clusterconfig/fastpass-jungle-cruise.yaml --nodes 10.1.71.69
+
+# Wait for node to reboot and come back online
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+
+# haunted-mansion
+talosctl apply-config --file clusterconfig/fastpass-haunted-mansion.yaml --nodes 10.1.71.70
+kubectl wait --for=condition=Ready node/haunted-mansion --timeout=10m
+
+# peter-pans-flight
+talosctl apply-config --file clusterconfig/fastpass-peter-pans-flight.yaml --nodes 10.1.71.71
+kubectl wait --for=condition=Ready node/peter-pans-flight --timeout=10m
+```
+
+### 4. Verify iSCSI is Working
+
+After each node reboots:
+
+```bash
+NODE_IP=10.1.71.69  # Change for each node
+
+# Check iscsid service is running
+talosctl -n $NODE_IP service iscsid
+
+# Verify kernel modules loaded
+talosctl -n $NODE_IP read /proc/modules | grep -E "iscsi_tcp|dm_multipath|dm_round_robin"
+
+# Check initiator name is set (unique per node)
+talosctl -n $NODE_IP read /etc/iscsi/initiatorname.iscsi
+
+# Verify /var/lib/iscsi exists and is writable
+talosctl -n $NODE_IP ls /var/lib/iscsi
+
+# Check kubelet is using correct nodeIP
+kubectl get node -o wide | grep jungle-cruise
+# Should show 10.1.71.69 as INTERNAL-IP, NOT 10.1.75.69
+```
+
+### 5. Configure Multipath (Post-Boot)
+
+Create a DaemonSet to configure multipath on all worker nodes:
+
+```bash
+cat > ~/git/homelab/talos/iscsi-multipath-init.yaml <<'EOF'
+apiVersion: apps/v1
+kind: DaemonSet
+metadata:
+  name: iscsi-multipath-init
+  namespace: kube-system
+spec:
+  selector:
+    matchLabels:
+      app: iscsi-multipath-init
+  template:
+    metadata:
+      labels:
+        app: iscsi-multipath-init
+    spec:
+      hostNetwork: true
+      hostPID: true
+      nodeSelector:
+        node-role.kubernetes.io/worker: ""
+      initContainers:
+      - name: configure-multipath
+        image: alpine:3.18
+        securityContext:
+          privileged: true
+        command:
+        - sh
+        - -c
+        - |
+          cat > /host/etc/multipath.conf <<'MPCONF'
+          defaults {
+              polling_interval 10
+              find_multipaths yes
+              user_friendly_names no
+          }
+          devices {
+              device {
+                  vendor "PURE"
+                  product "FlashArray"
+                  path_selector "service-time 0"
+                  path_grouping_policy group_by_prio
+                  prio alua
+                  path_checker tur
+                  fast_io_fail_tmo 10
+                  user_friendly_names no
+                  no_path_retry 0
+                  hardware_handler "1 alua"
+                  dev_loss_tmo 600
+                  failback immediate
+              }
+          }
+          blacklist {
+              devnode "^pxd[0-9]*"
+          }
+          MPCONF
+          
+          echo "Multipath configuration applied"
+          nsenter -t 1 -m -u -i -n -- multipath -ll || true
+        volumeMounts:
+        - name: host-etc
+          mountPath: /host/etc
+      containers:
+      - name: pause
+        image: registry.k8s.io/pause:3.9
+      volumes:
+      - name: host-etc
+        hostPath:
+          path: /etc
+          type: Directory
+EOF
+
+kubectl apply -f ~/git/homelab/talos/iscsi-multipath-init.yaml
+```
+
+Wait for DaemonSet to run on all workers:
+
+```bash
+kubectl rollout status daemonset/iscsi-multipath-init -n kube-system
+```
+
+### 6. Verify Multipath Configuration
+
+```bash
+for node in 10.1.71.69 10.1.71.70 10.1.71.71; do
+  echo "=== Checking $node ==="
+  talosctl -n $node read /etc/multipath.conf
+  talosctl -n $node exec -- multipath -ll
+done
+```
+
+## Portworx-Specific Considerations
+
+### 1. Ensure Portworx Uses Correct Network
+
+Portworx should use the **iSCSI network (10.1.75.x)** for storage traffic. Configure this in the Portworx StorageCluster CR:
+
+```yaml
+apiVersion: core.libopenstorage.org/v1
+kind: StorageCluster
+metadata:
+  name: px-cluster-fastpass
+  namespace: portworx
+spec:
+  network:
+    dataInterface: ens19     # iSCSI network
+    mgmtInterface: ens18     # Management network
+```
+
+### 2. Node Labels for Storage Network
+
+Label worker nodes to indicate iSCSI capability:
+
+```bash
+kubectl label node jungle-cruise storage-network=iscsi
+kubectl label node haunted-mansion storage-network=iscsi
+kubectl label node peter-pans-flight storage-network=iscsi
+```
+
+### 3. Verify Pure FlashArray Connectivity
+
+From any worker node:
+
+```bash
+# Discover iSCSI targets (replace with your FlashArray iSCSI IP)
+talosctl -n 10.1.71.69 exec -- iscsiadm -m discovery -t st -p <flasharray-iscsi-ip>
+
+# Example with 10.1.75.100 as FlashArray iSCSI endpoint
+talosctl -n 10.1.71.69 exec -- iscsiadm -m discovery -t st -p 10.1.75.100
+```
+
+Expected output:
+```
+10.1.75.100:3260,1 iqn.2010-06.com.purestorage:flasharray.xxxxx
+10.1.75.101:3260,2 iqn.2010-06.com.purestorage:flasharray.xxxxx
+```
+
+## Troubleshooting
+
+### If Boot Still Fails
+
+1. **Remove all files sections** and use only Option 1
+2. **Check Talos logs during boot:**
+   ```bash
+   talosctl -n <node-ip> dmesg | grep -i "write\|fail\|error"
+   talosctl -n <node-ip> logs controller-runtime
+   ```
+
+### If Kubelet Uses Wrong IP
+
+Check node internal IP:
+```bash
+kubectl get nodes -o wide
+```
+
+If showing 10.1.75.x instead of 10.1.71.x, the `nodeIP.validSubnets` didn't apply. Verify talconfig.yaml and regenerate.
+
+### If iSCSI Sessions Don't Connect
+
+```bash
+# Check iscsid is running
+talosctl -n <node-ip> service iscsid
+
+# Check kernel modules
+talosctl -n <node-ip> exec -- lsmod | grep iscsi_tcp
+
+# Try manual discovery
+talosctl -n <node-ip> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
+
+# Check for firewall issues on ens19
+talosctl -n <node-ip> exec -- ping <flasharray-ip>
+```
+
+## Summary of Changes
+
+| Issue | Old Config | New Config |
+|-------|-----------|-----------|
+| `/etc/iscsi` mount | ✗ Mounted (causes boot failure) | ✓ Removed (extension manages it) |
+| `/var/lib/iscsi` mount | ✓ Correct | ✓ Kept with `rw` option |
+| `multipath.conf` | ✗ Written at boot with `op: create` | ✓ Applied post-boot via DaemonSet |
+| Dual NIC handling | ✗ No nodeIP specified | ✓ `nodeIP.validSubnets` set to 10.1.71.0/24 |
+| File operation | `op: create` | N/A (moved to DaemonSet) |
+

+# jungle-cruise Node Recovery Procedure
+
+**Status:** Node NotReady since 2026-06-20 22:01 CDT  
+**Root Cause:** multipath.conf in machine.files causes boot failure  
+**Fix Applied:** Commit d2b6d95 - removed multipath.conf from machine.files  
+
+---
+
+## Problem Summary
+
+### What Happened
+
+1. **21:56 CDT** - Commit adc415e added `/etc/multipath.conf` to `machine.files` section
+2. **~22:00 CDT** - Configuration applied to jungle-cruise
+3. **22:01 CDT** - jungle-cruise kubelet stopped posting status (Node → NotReady)
+
+### Root Cause
+
+Writing `/etc/multipath.conf` during Talos early boot via `machine.files` causes:
+```
+[talos] writeUserFiles failed: permission denied (read-only filesystem)
+[talos] rebooting in 35 minutes
+```
+
+This is the SAME issue that was previously fixed in commit e8303d5 and documented in IMPLEMENTATION_REPORT.md.
+
+### Why This Happened
+
+The multipath.conf was correctly REMOVED in commit e8303d5 (with DaemonSet solution), but was inadvertently RE-ADDED in commit adc415e to fix PX-CSI node driver crash.
+
+---
+
+## Current State
+
+### Node Status
+```bash
+$ kubectl get node jungle-cruise
+NAME            STATUS     ROLES    AGE   VERSION
+jungle-cruise   NotReady   worker   47h   v1.32.3
+
+$ kubectl describe node jungle-cruise | grep Ready
+Ready                Unknown   ... NodeStatusUnknown   Kubelet stopped posting node status.
+```
+
+### Network Status
+- ✅ Node is pingable (10.1.71.69)
+- ✅ Talos API port is open (50000/tcp)
+- ❌ SSH not available (Talos doesn't run SSH)
+- ❌ Kubelet not posting status since 03:01:12Z
+
+### Pods on Node
+- All system pods (cilium, kube-proxy, etc.) are Pending
+- Cannot be scheduled due to Node NotReady
+
+---
+
+## Fix Applied
+
+**Commit:** d2b6d95  
+**Date:** 2026-06-20 22:07 CDT  
+**Changes:** Removed `machine.files` section containing multipath.conf from talconfig.yaml
+
+```diff
+-        # Write multipath.conf for PX-CSI
+-        files:
+-          - content: |
+-              defaults { ... }
+-              devices { ... }
+-            path: /etc/multipath.conf
+-            permissions: 0644
++        # (removed - use DaemonSet instead)
+```
+
+---
+
+## Recovery Procedure
+
+### Prerequisites
+
+- [ ] Access to talosctl with valid talosconfig (from city-hall or control plane)
+- [ ] SOPS/age keys to decrypt talsecret.sops.yaml (if regenerating configs)
+- [ ] OR access to existing clusterconfig/ directory with pre-generated configs
+
+### Option A: Apply Fixed Config (Preferred)
+
+If you have existing clusterconfig/ or can regenerate:
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# If clusterconfig/ doesn't exist, regenerate (requires SOPS keys)
+talhelper genconfig
+
+# Apply the fixed configuration to jungle-cruise
+talosctl apply-config \
+  --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+
+# Wait for node to reboot and become Ready
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+```
+
+### Option B: Force Reboot (Quick Recovery)
+
+If the node is stuck in a boot loop, a simple reboot might clear the bad state:
+
+```bash
+# Via talosctl
+talosctl --nodes 10.1.71.69 reboot
+
+# OR via Proxmox (if talosctl unavailable)
+# Find VM ID and reboot from Proxmox UI or CLI
+```
+
+After reboot, the node should come back with its previous (working) configuration, since the bad config hasn't been permanently written.
+
+### Option C: Full Config Regeneration
+
+If clusterconfig/ is missing:
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# Ensure SOPS age key is available
+export SOPS_AGE_KEY_FILE=~/.config/sops/age/keys.txt
+
+# Regenerate all configs
+talhelper genconfig
+
+# Apply to jungle-cruise only
+talosctl apply-config \
+  --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+
+# Monitor
+kubectl get nodes -w
+```
+
+---
+
+## Post-Recovery Steps
+
+### 1. Verify Node is Healthy
+
+```bash
+# Check node status
+kubectl get nodes -o wide
+# jungle-cruise should show Ready with INTERNAL-IP 10.1.71.69
+
+# Verify system pods are running
+kubectl get pods -n kube-system -o wide | grep jungle-cruise
+```
+
+### 2. Deploy multipath.conf DaemonSet
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# Deploy the DaemonSet that writes multipath.conf POST-boot
+kubectl apply -f iscsi-multipath-init.yaml
+
+# Verify it's running
+kubectl get pods -n kube-system -l app=iscsi-multipath-init -o wide
+```
+
+### 3. Verify iSCSI Configuration
+
+```bash
+# Check multipath config was written
+talosctl --nodes 10.1.71.69 read /etc/multipath.conf
+
+# Verify kernel modules
+talosctl --nodes 10.1.71.69 read /proc/modules | grep -E "iscsi|multipath"
+
+# Check iscsid service
+talosctl --nodes 10.1.71.69 service iscsid
+```
+
+### 4. Test PX-CSI
+
+Once multipath.conf is deployed via DaemonSet:
+
+```bash
+# Check PX-CSI node-plugin logs
+kubectl logs -n portworx -l name=portworx-node -c node-plugin | grep multipath
+
+# Should no longer see: "/etc/multipath.conf not found"
+```
+
+---
+
+## Why This Fix Works
+
+### ❌ BROKEN: machine.files (Early Boot)
+```yaml
+worker:
+  patches:
+    - machine:
+        files:  # Writes during early boot → FAILS on read-only FS
+          - path: /etc/multipath.conf
+            content: |
+              ...
+```
+
+### ✅ FIXED: DaemonSet (Post-Boot)
+```yaml
+apiVersion: apps/v1
+kind: DaemonSet
+metadata:
+  name: iscsi-multipath-init
+  namespace: kube-system
+spec:
+  template:
+    spec:
+      initContainers:
+      - name: configure-multipath
+        command:
+        - sh
+        - -c
+        - |
+          # Writes AFTER boot when FS is fully writable
+          cat > /host/etc/multipath.conf <<'MPCONF'
+          ...
+          MPCONF
+```
+
+**Key Difference:**
+- `machine.files` writes during early boot when `/etc` may be read-only
+- DaemonSet writes after Kubernetes is up and filesystem is fully writable

+# Talos iSCSI Quick Reference
+
+## Quick Start
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# Apply the fix
+./apply-iscsi-fix.sh
+
+# Verify after deployment
+./verify-iscsi.sh <flasharray-iscsi-ip>
+```
+
+## What Changed
+
+| Component | Before (BROKEN) | After (FIXED) |
+|-----------|----------------|---------------|
+| `/etc/iscsi` mount | ✗ Mounted → boot failure | ✓ Removed |
+| `/var/lib/iscsi` mount | `bind, rshared` | `bind, rshared, rw` |
+| Multipath config | Written at boot | DaemonSet post-boot |
+| Node IP | Auto-selected (wrong) | Explicit `10.1.71.0/24` |
+| Boot result | **FAILS** | **WORKS** |
+
+## Key Commands
+
+### Check Node Status
+```bash
+kubectl get nodes -o wide
+# All workers should show 10.1.71.x as INTERNAL-IP
+```
+
+### Verify iSCSI on a Node
+```bash
+NODE_IP=10.1.71.69
+
+# Service status
+talosctl -n $NODE_IP service iscsid
+
+# Modules loaded
+talosctl -n $NODE_IP read /proc/modules | grep -E "iscsi|multipath"
+
+# Initiator name
+talosctl -n $NODE_IP read /etc/iscsi/initiatorname.iscsi
+
+# Multipath config
+talosctl -n $NODE_IP read /etc/multipath.conf
+
+# Multipath devices
+talosctl -n $NODE_IP exec -- multipath -ll
+```
+
+### Test FlashArray Discovery
+```bash
+# Replace with your FlashArray iSCSI IP
+FLASHARRAY_IP=10.1.75.100
+
+talosctl -n 10.1.71.69 exec -- \
+  iscsiadm -m discovery -t st -p $FLASHARRAY_IP
+```
+
+### Check Multipath DaemonSet
+```bash
+kubectl get daemonset -n kube-system iscsi-multipath-init
+kubectl get pods -n kube-system -l app=iscsi-multipath-init -o wide
+```
+
+## Troubleshooting
+
+### Node Not Ready After Update
+```bash
+# Check dmesg for errors
+talosctl -n <node-ip> dmesg | grep -i "error\|fail"
+
+# Check Talos logs
+talosctl -n <node-ip> logs controller-runtime
+
+# Rollback if needed
+git checkout HEAD^ -- talconfig.yaml
+talhelper genconfig
+talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
+```
+
+### Wrong Node IP (10.1.75.x instead of 10.1.71.x)
+```bash
+# Verify talconfig has nodeIP.validSubnets
+grep -A 3 "nodeIP:" talconfig.yaml
+
+# Should show:
+#   nodeIP:
+#     validSubnets:
+#       - 10.1.71.0/24
+
+# If missing, edit talconfig.yaml and reapply
+```
+
+### Multipath Config Missing
+```bash
+# Check DaemonSet is running
+kubectl get pods -n kube-system -l app=iscsi-multipath-init
+
+# If not deployed:
+kubectl apply -f iscsi-multipath-init.yaml
+
+# Force recreation
+kubectl delete pod -n kube-system -l app=iscsi-multipath-init
+```
+
+### iSCSI Discovery Fails
+```bash
+# Check network connectivity on ens19
+talosctl -n <node-ip> exec -- ip addr show ens19
+talosctl -n <node-ip> exec -- ping -c 3 <flasharray-ip>
+
+# Check iscsid service
+talosctl -n <node-ip> service iscsid
+
+# Start iscsid if needed (auto-starts on discovery)
+talosctl -n <node-ip> exec -- \
+  iscsiadm -m discovery -t st -p <flasharray-ip>
+```

+# Talos iSCSI Configuration for Portworx CSI
+
+This directory contains the fixed Talos configuration for iSCSI support on worker nodes, enabling Portworx CSI driver integration with Pure Storage FlashArray.
+
+## 🚨 Problem Statement
+
+The initial iSCSI configuration (commit f370213) caused worker nodes to fail boot with:
+```
+writeUserFiles failed, rebooting in 35 minutes
+```
+
+This was caused by:
+1. Mounting `/etc/iscsi` (conflicts with iscsi-tools extension)
+2. Writing `/etc/multipath.conf` during early boot (filesystem not writable)
+3. Missing explicit nodeIP configuration for dual-NIC workers
+
+## ✅ Solution
+
+The fix involves three changes:
+
+1. **Remove `/etc/iscsi` mount** - Let iscsi-tools extension manage it
+2. **Add explicit nodeIP** - Bind kubelet to primary network (10.1.71.0/24)
+3. **Move multipath config to DaemonSet** - Configure post-boot when filesystem is writable
+
+## 📋 Files in This Directory
+

+
+## 🚀 Quick Start
+
+### 1. Review the Changes
+
+```bash
+cd ~/git/homelab/talos/talhelper
+
+# See what changed
+git diff <previous-commit> talconfig.yaml
+
+# Read the detailed documentation
+cat ISCSI_CONFIG_FIX.md
+```
+
+### 2. Apply the Fix
+
+```bash
+# Dry run first to preview
+./apply-iscsi-fix.sh --dry-run
+
+# Apply to all worker nodes
+./apply-iscsi-fix.sh
+```
+
+This script will:
+- Regenerate Talos configs
+- Apply to each worker sequentially (jungle-cruise → haunted-mansion → peter-pans-flight)
+- Wait for each node to reboot and become Ready
+- Verify iSCSI functionality
+- Deploy multipath DaemonSet
+
+**Duration:** ~20-30 minutes (3 nodes × 5-10 min each)
+
+### 3. Verify
+
+```bash
+# Run comprehensive verification (replace with your FlashArray iSCSI IP)
+./verify-iscsi.sh 10.1.75.100
+
+# Check node IPs (should be 10.1.71.x, NOT 10.1.75.x)
+kubectl get nodes -o wide
+
+# Check multipath DaemonSet
+kubectl get pods -n kube-system -l app=iscsi-multipath-init -o wide
+```
+
+## 🔧 Manual Application (if needed)
+
+If you prefer manual control:
+
+```bash
+# Regenerate config
+talhelper genconfig
+
+# Apply to one worker at a time
+talosctl apply-config \
+  --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+
+# Wait for Ready
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+
+# Verify
+talosctl -n 10.1.71.69 service iscsid
+talosctl -n 10.1.71.69 read /etc/iscsi/initiatorname.iscsi
+
+# Repeat for other nodes...
+```

+└─────────────────────────────────────────────────────────────┘
+```
+
+**Key insight:** By moving multipath configuration to a DaemonSet (step 6), we avoid writing files during early boot when the filesystem may not be writable.
+
+## 🌐 Network Configuration
+
+Workers have dual NICs:
+
+| Interface | Network | Purpose |
+|-----------|---------|---------|
+| **ens18** | 10.1.71.0/24 | **Primary** - Kubernetes API, pod traffic |
+| **ens19** | 10.1.75.0/24 | **Storage** - iSCSI to FlashArray |
+
+**Critical:** Kubelet must bind to ens18 (10.1.71.x) using `nodeIP.validSubnets`.

+## ✅ Success Criteria
+
+After deployment, verify:
+
+- [ ] All worker nodes show `Ready` status
+- [ ] Node IPs are `10.1.71.x` (not `10.1.75.x`)
+- [ ] `iscsi-tools` extension loaded
+- [ ] Kernel modules loaded: `iscsi_tcp`, `dm_multipath`, `dm_round_robin`
+- [ ] `iscsid` service ready
+- [ ] `/var/lib/iscsi` directory accessible
+- [ ] Unique initiator name on each node
+- [ ] `/etc/multipath.conf` exists with Pure Storage config
+- [ ] `ens19` interface up with `10.1.75.x` IP
+- [ ] Multipath DaemonSet running on all workers
+- [ ] No boot errors in `dmesg`
+
+## 🆘 Troubleshooting
+
+### Boot Failure
+
+If a node fails to boot after applying config:
+
+```bash
+# Check dmesg for errors
+talosctl -n <node-ip> dmesg | grep -i "error\|fail"
+
+# Check Talos controller logs
+talosctl -n <node-ip> logs controller-runtime
+
+# Rollback
+git checkout HEAD^ -- talconfig.yaml
+talhelper genconfig
+talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
+```
+
+### Wrong Node IP
+
+If kubelet binds to `10.1.75.x` instead of `10.1.71.x`:
+
+```bash
+# Verify nodeIP.validSubnets in config
+grep -A 3 "nodeIP:" talconfig.yaml
+
+# Should show:
+#   nodeIP:
+#     validSubnets:
+#       - 10.1.71.0/24
+
+# If missing, add it and reapply
+```
+
+### iSCSI Not Working
+
+```bash
+# Full verification
+./verify-iscsi.sh <flasharray-ip>
+
+# Check specific components
+talosctl -n <node-ip> service iscsid
+talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
+talosctl -n <node-ip> exec -- multipath -ll
+
+# Test discovery
+talosctl -n <node-ip> exec -- \
+  iscsiadm -m discovery -t st -p <flasharray-iscsi-ip>
+```
+
+## 🔄 Next Steps
+
+After successful deployment:
+
+1. **Deploy Portworx CSI** (if not already deployed)
+   ```bash
+   cd ~/git/homelab/cluster/platform/portworx-csi
+   cat README.md
+   ```
+
+2. **Test iSCSI to FlashArray**
+   ```bash
+   ./verify-iscsi.sh <flasharray-iscsi-ip>
+   ```
+
+3. **Create test PVC**
+   ```yaml
+   apiVersion: v1
+   kind: PersistentVolumeClaim
+   metadata:
+     name: test-pure-block
+   spec:
+     accessModes: [ReadWriteOnce]
+     storageClassName: pure-block
+     resources:
+       requests:
+         storage: 10Gi
+   ```
+
+4. **Monitor Portworx**
+   ```bash
+   kubectl logs -n portworx -l app=portworx-operator -f
+   ```

+# Task Completion Summary: jungle-cruise Node Recovery
+
+**Task:** Diagnose and fix jungle-cruise node failure after adding multipath.conf to Talos worker configuration  
+**Date:** 2026-06-20  
+**Agent:** Hermes (carousel-of-progress)  
+**Status:** Diagnosis Complete ✅ | Fix Applied ✅ | Node Recovery Pending ⏳
+
+---
+
+## What I Did
+
+### 1. Root Cause Analysis ✅
+
+**Problem Identified:**
+- Commit `adc415e` (2026-06-20 21:56) added `/etc/multipath.conf` to `machine.files` section
+- Configuration was applied to jungle-cruise around 22:00
+- Node went NotReady at 22:01 (kubelet stopped posting status)
+
+**Root Cause:**
+```
+Writing /etc/multipath.conf during Talos early boot via machine.files
+causes writeUserFiles to fail on read-only filesystem, triggering
+automatic reboot cycle.
+```
+
+**Evidence:**
+- This is the SAME issue previously fixed in commit `e8303d5` 
+- IMPLEMENTATION_REPORT.md clearly documents this failure mode
+- Previous fix correctly used DaemonSet approach
+- Multipath.conf was inadvertently re-added via machine.files
+
+### 2. Configuration Fixed ✅
+
+**Commit:** `d2b6d95` - "Revert multipath.conf from machine.files"  
+**Changes:**
+- Removed entire `machine.files` section from worker patches in talconfig.yaml
+- Restored configuration to working state (matching commit e8303d5)
+- DaemonSet approach (iscsi-multipath-init.yaml) is still available for post-boot config
+
+**Git History:**
+```
+a30ad99 - Add jungle-cruise recovery documentation
+d2b6d95 - Revert multipath.conf from machine.files
+adc415e - Add multipath.conf for PX-CSI node driver (BROKE NODE)
+e8303d5 - Fix Talos iSCSI configuration for Portworx CSI (WORKING)
+```
+
+### 3. Documentation Created ✅
+
+**Files Created:**
+- `JUNGLE-CRUISE-RECOVERY.md` - Comprehensive recovery procedure
+- This summary document
+
+**Recovery Procedures Documented:**
+- Option A: Apply fixed config (requires talosctl + existing configs)
+- Option B: Force reboot via talosctl or Proxmox (quickest)
+- Option C: Full regeneration (requires SOPS/age keys)

+## What I Found
+
+### Node Current State
+
+```
+Name:               jungle-cruise
+IP:                 10.1.71.69
+Status:             NotReady (since 2026-06-20 22:01 CDT)
+Reason:             NodeStatusUnknown - Kubelet stopped posting node status
+Last Heartbeat:     2026-06-21 03:00:07Z
+Network:            ✅ Pingable, Talos API port (50000) open
+SSH:                ❌ Not available (Talos doesn't run SSH)
+Pods:               All Pending (cannot schedule on NotReady node)
+```
+
+### Configuration State
+
+```
+Git Status:         Fixed configuration committed
+talconfig.yaml:     ✅ Corrected (multipath.conf removed from machine.files)
+DaemonSet:          ✅ iscsi-multipath-init.yaml ready for deployment
+Cluster Configs:    ❌ Not generated (requires SOPS/age keys OR city-hall access)
+```
+
+### Access Limitations
+
+**What I Have:**
+- ✅ kubectl access (full cluster admin)
+- ✅ Git repository access
+- ✅ Node network connectivity (ping, API port open)
+- ✅ Downloaded talosctl v1.13.2
+- ✅ Downloaded talhelper v3.1.11
+- ✅ Downloaded sops v3.9.4
+
+**What I Don't Have:**
+- ❌ Working talosconfig (file exists but empty at ~/.talos/config)
+- ❌ SOPS/age private keys (~/.config/sops/age/keys.txt doesn't exist)
+- ❌ SSH access to jungle-cruise (Talos doesn't run SSH)
+- ❌ Access to city-hall (management node with credentials)
+- ❌ Pre-generated clusterconfig/ directory
+
+**Why I Can't Complete Recovery:**
+- Applying Talos config requires authenticated talosctl connection
+- Generating new configs requires SOPS keys to decrypt talsecret.sops.yaml
+- Cannot SSH to node to force reboot
+- Cannot schedule pods on NotReady node to trigger reboot
+
+---
+
+## What Needs to Happen Next
+
+### Immediate Action Required
+
+Someone with ONE of the following needs to complete recovery:
+
+#### Option 1: Apply Fixed Config (Recommended)
+```bash
+# On city-hall or host with talosconfig
+cd ~/git/homelab/talos/talhelper
+git pull  # Get commits d2b6d95 and a30ad99
+talhelper genconfig
+talosctl apply-config \
+  --file clusterconfig/fastpass-jungle-cruise.yaml \
+  --nodes 10.1.71.69
+kubectl wait --for=condition=Ready node/jungle-cruise --timeout=10m
+```
+
+#### Option 2: Force Reboot (Quickest)
+```bash
+# Via talosctl
+talosctl --nodes 10.1.71.69 reboot
+
+# OR via Proxmox
+# Find jungle-cruise VM and reboot from UI
+```
+
+#### Option 3: Deploy DaemonSet After Recovery
+```bash
+# Once node is back to Ready
+kubectl apply -f iscsi-multipath-init.yaml
+kubectl get pods -n kube-system -l app=iscsi-multipath-init -o wide
+```
+
+### Verification Steps
+
+After recovery:
+```bash
+# 1. Node is Ready
+kubectl get nodes -o wide | grep jungle-cruise
+
+# 2. Multipath config deployed via DaemonSet
+kubectl logs -n kube-system -l app=iscsi-multipath-init
+
+# 3. PX-CSI no longer crashes
+kubectl logs -n portworx -l name=portworx-node -c node-plugin | grep multipath
+```

+## Files Modified
+
+| File | Status | Description |
+|------|--------|-------------|

+| JUNGLE-CRUISE-RECOVERY.md | ✅ Created | Recovery procedures |
+| TASK-SUMMARY.md | ✅ Created | This document |

+
+## Key Learnings
+
+### What Worked
+
+1. **Systematic diagnosis** - Git history showed exactly when/why failure occurred
+2. **Existing documentation** - IMPLEMENTATION_REPORT.md had the answer
+3. **Git rollback** - Reverting to working config was straightforward
+4. **kubectl access** - Could monitor node status and cluster state
+
+### What Didn't Work
+
+1. **talosconfig retrieval** - No valid config found on this host
+2. **SOPS decryption** - Missing age keys prevented config regeneration
+3. **Remote reboot** - No SSH, can't schedule pods on NotReady node
+4. **Cross-host access** - Couldn't reach city-hall for credentials
+
+### Recommendations
+
+1. **Store talosconfig in 1Password** - Easy retrieval from any host
+2. **Document key locations** - Age key path should be in runbook
+3. **Pre-generate configs** - Keep clusterconfig/ in git (they're machine-specific, not secrets)
+4. **Test recovery procedures** - Practice node recovery before needing it
+5. **Never bypass previous fixes** - Commit e8303d5 solved this; should have kept that approach
+

+
+## Next Steps for Operations Team
+
+1. **Pull latest git commits** (d2b6d95, a30ad99)
+2. **Review JUNGLE-CRUISE-RECOVERY.md**
+3. **Choose recovery option** based on available credentials
+4. **Execute recovery procedure**
