# 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 |
|
||||
|------|--------|-------------|
|
||||
| talconfig.yaml | ✅ Fixed | Removed machine.files section |
|
||||
| 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
