# 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
|
|
```
|
|

## 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
