**Date:** 2025-01-20  
**Status:** ✅ Complete  
**Result:** Cluster node names now match system hostnames

---

## ✅ Fix Complete

Cluster node names have been successfully updated to match system hostnames.

---

## Before and After

### Before
```
Cluster Nodes:
- Node 1: ml110 ✅
- Node 2: pve ⚠️ (system hostname: r630-01)
- Node 3: pve2 ⚠️ (system hostname: r630-02)
```

### After
```
Cluster Nodes:
- Node 1: ml110 ✅
- Node 2: r630-01 ✅
- Node 3: r630-02 ✅
```

---

## Changes Made

### 1. Updated corosync.conf
**File:** `/etc/pve/corosync.conf`  
**Changes:**
- Node name: `pve` → `r630-01`
- Node name: `pve2` → `r630-02`
- Config version: 3 → 4

**Backup Created:** `/etc/pve/corosync.conf.backup.*`

### 2. Renamed Node Directories
- `/etc/pve/nodes/pve` → `/etc/pve/nodes/r630-01`
- `/etc/pve/nodes/pve2` → `/etc/pve/nodes/r630-02`

### 3. Restarted Corosync

## Configuration Details

### corosync.conf
```conf
nodelist {
  node {
    name: ml110
    nodeid: 1
    quorum_votes: 1
    ring0_addr: 192.168.11.10
  }
  node {
    name: r630-01
    nodeid: 2
    quorum_votes: 1
    ring0_addr: 192.168.11.11
  }
  node {
    name: r630-02
    nodeid: 3
    quorum_votes: 1
    ring0_addr: 192.168.11.12
  }
}
```

## Verification Commands

### Check Cluster Nodes
```bash
pvecm nodes
# Should show: ml110, r630-01, r630-02
```

### Check Cluster Status
```bash
pvecm status
# Should show: Quorate: Yes, Nodes: 3
```

### Check Node Information
```bash
pvesh get /nodes
# Should list: ml110, r630-01, r630-02
```

## Impact

### What Changed
- ✅ Cluster node names now match system hostnames
- ✅ Consistency across system and cluster
- ✅ Easier identification and management
- ✅ Documentation alignment

### What Didn't Change
- ✅ Cluster functionality (fully operational)
- ✅ Node IDs (unchanged: 1, 2, 3)
- ✅ IP addresses (unchanged)
- ✅ Cluster configuration (except node names)
- ✅ VM/Container operations (unchanged)

---

## Scripts Updated

### Created
- `scripts/fix-cluster-node-names.sh` - Script to update cluster node names

### Usage
```bash
./scripts/fix-cluster-node-names.sh
```

---

## Consistency Achieved

### System Hostnames
- ml110: ✅ ml110
- r630-01: ✅ r630-01
- r630-02: ✅ r630-02

### Cluster Node Names
- Node 1: ✅ ml110
- Node 2: ✅ r630-01
- Node 3: ✅ r630-02

### Documentation
- ✅ All naming consistent
- ✅ No confusion between old and new names
- ✅ Clear identification

---

## Summary

✅ **All cosmetic issues fixed:**
- Cluster node names updated
- System hostnames match cluster node names
- All nodes operational
- Quorum maintained
