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.conftomachine.filessection - 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.filessection 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)
# 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)
# 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
# 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:
# 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
- Systematic diagnosis - Git history showed exactly when/why failure occurred
- Existing documentation - IMPLEMENTATION_REPORT.md had the answer
- Git rollback - Reverting to working config was straightforward
- kubectl access - Could monitor node status and cluster state
What Didn't Work
- talosconfig retrieval - No valid config found on this host
- SOPS decryption - Missing age keys prevented config regeneration
- Remote reboot - No SSH, can't schedule pods on NotReady node
- Cross-host access - Couldn't reach city-hall for credentials
Recommendations
- Store talosconfig in 1Password - Easy retrieval from any host
- Document key locations - Age key path should be in runbook
- Pre-generate configs - Keep clusterconfig/ in git (they're machine-specific, not secrets)
- Test recovery procedures - Practice node recovery before needing it
- Never bypass previous fixes - Commit
e8303d5solved this; should have kept that approach
