## Cluster Node Names vs System Hostnames

### Note on Node Names
The cluster node names (shown in `pvecm nodes`) still display old hostnames:
- **r630-01** shows as "pve" in cluster
- **r630-02** shows as "pve2" in cluster

**This is expected and normal:**
- Cluster node names are stored in corosync configuration
- They are separate from system hostnames
- Cluster functionality is **not affected**
- This is cosmetic only
- Nodes are fully functional and communicating correctly

**To change cluster node names (optional):**
- Requires cluster reconfiguration
- Not necessary for functionality
- Can be done if desired for consistency

## Cluster Connectivity Test

### From r630-01
```bash
ssh root@192.168.11.11
pvecm status
# Result: ✅ All nodes visible, quorum yes
```

### From r630-02
```bash
ssh root@192.168.11.12
pvecm status
# Result: ✅ All nodes visible, quorum yes
```

### From ml110 (Main Node)
```bash
ssh root@192.168.11.10
pvecm status
# Result: ✅ All nodes visible, quorum yes
```

## Join Information Match

The provided join information matches the cluster configuration:
- ✅ Cluster name: "h"
- ✅ Main node IP: 192.168.11.10
- ✅ Config version: 3
- ✅ Secure auth: enabled
- ✅ All nodes connected with this configuration

---

## Cluster Operations

### Available Operations
- ✅ VM/Container migration between nodes
- ✅ Shared storage access
- ✅ High availability (if configured)
- ✅ Cluster-wide operations
- ✅ Resource pooling

### Verification Commands
```bash
# Check cluster status
pvecm status

# List cluster nodes
pvecm nodes

# Check node information
pvesh get /nodes/<node-name>/status

# List all nodes
pvesh get /nodes
```

## Recommendations

### Current Status: ✅ Excellent
- All nodes connected
- Quorum maintained
- No connectivity issues
- Cluster fully operational

### Optional Improvements
1. **Cluster Node Names** (cosmetic)
   - Can update cluster node names to match hostnames
   - Not required for functionality
   - Requires cluster reconfiguration

2. **Monitoring**
   - Set up cluster monitoring
   - Alert on quorum loss
   - Monitor cluster health

3. **Documentation**
   - Document cluster configuration
   - Document recovery procedures
   - Maintain join information securely

---

## Conclusion

✅ **Both servers (192.168.11.11 and 192.168.11.12) are successfully connected to the Proxmox VE cluster.**

- **Cluster Status:** Operational
- **Quorum:** Yes (Quorate)
