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

ssh root@192.168.11.11
pvecm status
# Result: ✅ All nodes visible, quorum yes

From r630-02

ssh root@192.168.11.12
pvecm status
# Result: ✅ All nodes visible, quorum yes

From ml110 (Main Node)

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

# 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)
• All Nodes: Connected and communicating
• Configuration: Matches provided join information
• Health: Excellent

The cluster is fully operational and ready for production use.
