- [ ] **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

"APIToken": "paste-api-token-here",
"NFSEndPoint": "flasharray-nfs.mk-labs.cloud"
}
]
}
```
- Replace `flasharray.mk-labs.cloud` with actual endpoint
- Replace `paste-api-token-here` with FlashArray API token
- Remove `NFSEndPoint` line if not using File Services
- [ ] **Validate JSON syntax**
```bash
# Copy content from 1Password and validate
echo '<paste-json>' | jq .
```
- [ ] **Verify 1Password Connect can access item**
```bash

## 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`.

## 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]}'
```
## Maintenance

# 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

```
## 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:
# Install system extensions
install:
extensions:

ATTRS{vendor}=="PURE", ATTR{queue/nr_requests}="256"
# Enable iSCSI mounts in kubelet
kubelet:
extraMounts:
- destination: /var/lib/iscsi
type: bind
source: /var/lib/iscsi
options:
- 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
pure-block pxd.portworx.com Delete Immediate true
pure-file pxd.portworx.com Delete Immediate true
```
## Usage
### Create a PVC with Block Storage
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: postgres-data
namespace: default
spec:
accessModes:
- ReadWriteOnce
storageClassName: pure-block
resources:
requests:
storage: 10Gi
```
### Create a PVC with File Storage (NFS)
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: shared-data
namespace: default
spec:
accessModes:
- ReadWriteMany
storageClassName: pure-file
resources:
requests:
storage: 50Gi
```
### 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
```
### Volume Snapshots
```yaml
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
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

## 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

# Platform: portworx-csi
# Wave 2 — no secret dependencies initially; must be ready before stateful workloads
#
# Portworx CSI driver for Pure Storage FlashArray on Talos Linux
# Provides high-performance block and file storage for Kubernetes workloads
#
# Installation flow:
# 1. External Secrets Operator (wave 1) creates px-pure-secret from 1Password
# 2. Portworx Operator deploys (via Helm chart)
# 3. StorageCluster CR provisions CSI driver components
# 4. StorageClasses become available for PVC provisioning
#
# Prerequisites:
# - FlashArray configured with API token in 1Password
# - Talos nodes configured with multipath and udev rules (via MachineConfig)
# - iSCSI initiators enabled on all nodes
