+# Proxmox Cluster Configuration: sankofa-sfv-01
+
+**Last Updated**: 2024-12-19  
+**Cluster Name**: sankofa-sfv-01
+
+## Cluster Overview
+
+- **Cluster Name**: sankofa-sfv-01
+- **Node Count**: 2
+- **Status**: Active (verified via node visibility)
+
+## Cluster Nodes
+
+### Node 1: ML110-01
+- **IP**: 192.168.11.10
+- **FQDN**: ml110-01.sankofa.nexus
+- **Site**: us-sfvalley
+- **Status**: Online
+- **Cluster Role**: Primary/First Node
+
+### Node 2: R630-01
+- **IP**: 192.168.11.11
+- **FQDN**: r630-01.sankofa.nexus
+- **Site**: us-sfvalley-2
+- **Status**: Online
+- **Cluster Role**: Secondary/Second Node
+
+## Cluster Verification
+
+### Evidence of Cluster Existence
+
+✅ **Node Visibility**:
+- ML110-01 can see both nodes (r630-01 and ml110-01) in nodes list
+- This indicates cluster membership (standalone nodes only see themselves)
+
+### Verification Methods
+
+1. **Proxmox Web UI**:
+   - Log in to either node
+   - Navigate to: Datacenter → Cluster
+   - Verify cluster name: sankofa-sfv-01
+   - Verify both nodes listed
+
+2. **SSH Commands**:
+   ```bash
+   pvecm status
+   pvecm nodes
+   ```
+
+3. **Corosync Configuration**:
+   ```bash
+   cat /etc/pve/corosync.conf
+   ```
+
+## Quorum Configuration
+
+For a 2-node cluster, quorum must be explicitly configured:
+
+```bash
+# On both nodes
+pvecm expected 2
+pvecm status
+```
+
+**Important**: Without quorum configuration, a 2-node cluster may have issues if one node goes offline.
+
+## Cluster Features
+
+Once cluster is verified, you can:
+- ✅ Create VMs on either node
+- ✅ Migrate VMs between nodes
+- ✅ Manage storage across cluster
+- ✅ Use cluster-level operations
+
+## Network Configuration
+
+- **Cluster Network**: 192.168.11.0/24
+- **Corosync Ports**: 5404-5405 (should be open between nodes)
+- **API Port**: 8006 (HTTPS)
+
+## Storage Considerations
+
+- Each node has local storage
+- For shared storage, consider:
+  - NFS shares
+  - Ceph storage
+  - Shared LVM volumes
+
+## Monitoring
+
+- Cluster status: Check via Web UI or `pvecm status`
+- Node status: Check via Web UI or API
+- Quorum status: Check via `pvecm status`
+
+## Troubleshooting
+
+### Cluster Split-Brain
+
+If cluster splits:
+```bash
+# On majority node
+pvecm expected 2
+
+# On minority node (if needed)
+pvecm expected 1
+```
+
+### Node Cannot Join
+
+1. Check network connectivity
+2. Verify firewall rules
+3. Check corosync service: `systemctl status corosync`
+4. Review logs: `journalctl -u corosync`
