# Proxmox VE Fix Complete - pve and pve2

**Date:** 2025-01-20  
**Status:** ✅ **ALL ISSUES RESOLVED**

---

## Issues Fixed

### Root Cause
The primary issue was **hostname resolution failure**. The pve-cluster service could not resolve the hostname "pve" or "pve2" to a non-loopback IP address, causing:
- pve-cluster service to fail
- /etc/pve filesystem not mounting
- SSL certificates not accessible
- pveproxy workers crashing

### Error Message
```
Unable to resolve node name 'pve' to a non-loopback IP address - missing entry in '/etc/hosts' or DNS?
```

---

## Fixes Applied

### 1. Hostname Resolution Fix
**Script:** `scripts/fix-proxmox-hostname-resolution.sh`

**What it did:**
- Added proper entries to `/etc/hosts` on both hosts
- Ensured hostnames resolve to their actual IP addresses (not loopback)
- Added both current hostname (pve/pve2) and correct hostname (r630-01/r630-02)

**Results:**
- ✅ pve-cluster service started successfully on both hosts
- ✅ /etc/pve filesystem is now mounted
- ✅ SSL certificates are accessible

### 2. SSL and Cluster Service Fix
**Script:** `scripts/fix-proxmox-ssl-cluster.sh`

**What it did:**
- Regenerated SSL certificates
- Restarted all Proxmox services in correct order
- Verified service status

**Results:**
- ✅ All services running
- ✅ Web interface accessible (HTTP 200)
- ✅ No worker exit errors

## Current Status

### pve (192.168.11.11 - r630-01)

| Service | Status | Notes |
|---------|--------|-------|
| **pve-cluster** | ✅ Active (running) | Cluster filesystem mounted |
| **pvestatd** | ✅ Active (running) | Status daemon working |
| **pvedaemon** | ✅ Active (running) | API daemon working |
| **pveproxy** | ✅ Active (running) | Web interface accessible |
| **Web Interface** | ✅ Accessible | HTTP Status: 200 |
| **Port 8006** | ✅ Listening | Workers running normally |

### pve2 (192.168.11.12 - r630-02)

| Service | Status | Notes |
|---------|--------|-------|
| **pve-cluster** | ✅ Active (running) | Cluster filesystem mounted |
| **pvestatd** | ✅ Active (running) | Status daemon working |
| **pvedaemon** | ✅ Active (running) | API daemon working |
| **pveproxy** | ✅ Active (running) | Web interface accessible |
| **Web Interface** | ✅ Accessible | HTTP Status: 200 |
| **Port 8006** | ✅ Listening | Workers running normally |

## /etc/hosts Configuration

### pve (192.168.11.11)
```
192.168.11.11    pve pve.sankofa.nexus r630-01 r630-01.sankofa.nexus
```

### pve2 (192.168.11.12)
```
192.168.11.12    pve2 pve2.sankofa.nexus r630-02 r630-02.sankofa.nexus
```

**Key Point:** The hostname (pve/pve2) must resolve to the actual IP address (192.168.11.11/12), not to 127.0.0.1. This is required for pve-cluster to function.

---

## Cluster Status

Both nodes are in a cluster:
- **Cluster Name:** h
- **Config Version:** 3
- **Transport:** knet
- **Status:** Operational

---

## Verification

### Web Interface Access
```bash
# pve
curl -k https://192.168.11.11:8006/
# Returns: HTTP 200 ✅

# pve2
curl -k https://192.168.11.12:8006/
# Returns: HTTP 200 ✅
```

### Service Status
```bash
# Check services on pve
ssh root@192.168.11.11 "systemctl status pve-cluster pvestatd pvedaemon pveproxy"

# Check services on pve2
ssh root@192.168.11.12 "systemctl status pve-cluster pvestatd pvedaemon pveproxy"
```

### No Worker Exits
```bash
# Check for worker exit errors
ssh root@192.168.11.11 "journalctl -u pveproxy -n 50 | grep 'worker exit'"
# Should return: No recent worker exit errors ✅
```

## Scripts Created

1. **`scripts/diagnose-proxmox-hosts.sh`**
   - Comprehensive diagnostic tool
   - Tests connectivity, SSH, and all Proxmox services
   - Usage: `./scripts/diagnose-proxmox-hosts.sh [pve|pve2|both]`

2. **`scripts/fix-proxmox-hostname-resolution.sh`**
   - Fixes hostname resolution issues
   - Updates /etc/hosts with correct entries
   - Usage: `./scripts/fix-proxmox-hostname-resolution.sh`

3. **`scripts/fix-proxmox-ssl-cluster.sh`**
   - Fixes SSL and cluster service issues
   - Regenerates certificates and restarts services
   - Usage: `./scripts/fix-proxmox-ssl-cluster.sh [pve|pve2|both]`

## Lessons Learned

1. **Hostname Resolution is Critical**
   - Proxmox VE requires hostnames to resolve to non-loopback IPs
   - /etc/hosts must have proper entries
   - DNS alone may not be sufficient

2. **Service Dependencies**
   - pve-cluster must be running before other services
   - /etc/pve filesystem must be mounted for SSL certificates
   - Services must be started in correct order

3. **Cluster Filesystem**
   - pmxcfs (Proxmox Cluster File System) is required
   - It provides /etc/pve as a FUSE filesystem
   - Without it, SSL certificates and configuration are inaccessible

---

## Next Steps

1. ✅ **Monitor Services**
   - Watch for any worker exit errors
   - Verify web interface remains accessible

2. **Consider Hostname Migration**
   - Current hostnames: pve, pve2
   - Correct hostnames: r630-01, r630-02
   - Migration can be done later if needed (see HOSTNAME_MIGRATION_GUIDE.md)

3. **Document Cluster Configuration**
   - Document cluster setup
   - Note any cluster-specific requirements
