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)

# 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

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 e8303d5 solved this; should have kept that approach
