+# Next Steps Completed
+
+**Date**: 2024-12-19
+
+## Completed Steps
+
+### ✅ Step 1: Cluster Status Update
+- Updated TASK-040 with cluster findings
+- Marked cluster creation as completed (pending final verification)
+- Documented evidence: ML110-01 sees 2 nodes (cluster likely exists)
+- Cluster name: sankofa-sfv-01
+
+### ✅ Step 2: Configuration Review
+- Reviewed provider-config.yaml
+- Configuration appears correct for cluster setup
+
+### ✅ Step 3: Quorum Verification Script
+- Created `scripts/verify-cluster-quorum.sh`
+- Provides instructions for quorum configuration
+- Documents expected output
+
+### ✅ Step 4: Cluster Documentation
+- Created `docs/proxmox/CLUSTER_CONFIGURATION.md`
+- Comprehensive cluster configuration guide
+- Includes troubleshooting and monitoring
+
+## Cluster Status Summary
+
+**Cluster Name**: sankofa-sfv-01
+
+**Evidence of Cluster**:
+- ✅ ML110-01 can see 2 nodes (r630-01 and ml110-01)
+- ✅ Both nodes are online
+- ✅ Network connectivity confirmed
+
+**Pending Verification**:
+- ⚠️ Cluster name verification (requires Web UI or SSH)
+- ⚠️ Quorum configuration verification (requires SSH)
+- ⚠️ Final cluster status confirmation
+

+## Next Actions
+
+### Immediate (Can be done now)
+1. ✅ Cluster status documented
+2. ✅ Configuration files reviewed
+3. ✅ Documentation created
+
+### Requires External Access
+1. **Verify cluster via Web UI**:
+   - Log in to https://ml110-01.sankofa.nexus:8006
+   - Check Datacenter → Cluster
+   - Verify cluster name: sankofa-sfv-01
+
+2. **Configure quorum (if not done)**:
+   - SSH to both nodes
+   - Run: `pvecm expected 2`
+
+3. **Set up Kubernetes cluster**:
+   - Install kind, minikube, or use existing cluster
+   - Configure kubeconfig
+
+4. **Deploy Crossplane**:
+   - Install Crossplane in Kubernetes
+   - Build and deploy provider
+
+5. **Set up monitoring**:
+   - Deploy Prometheus exporters
+   - Configure Grafana dashboards
