## Final Results

### RPC Connectivity: 11/11 Nodes Responding ✅

| VMID | IP Address | Block Number | Status |
|------|------------|--------------|--------|
| 2101 | 192.168.11.211 | 1,145,367 | ✅ Synced |
| 2201 | 192.168.11.221 | 1,145,367 | ✅ Synced |
| 2303 | 192.168.11.233 | 1,145,367 | ✅ Synced |
| 2304 | 192.168.11.234 | 1,145,367 | ✅ Synced |
| 2305 | 192.168.11.235 | 1,145,367 | ✅ Synced |
| 2306 | 192.168.11.236 | 1,145,367 | ✅ Synced |
| 2307 | 192.168.11.237 | 1,145,367 | ✅ Synced |
| 2308 | 192.168.11.238 | 1,145,367 | ✅ Synced |
| 2401 | 192.168.11.241 | 1,149,992 | ✅ Synced |
| 2402 | 192.168.11.242 | 1,149,992 | ✅ Synced |
| 2403 | 192.168.11.243 | 600,172 | ⏳ Syncing |

### Container Status: 11/12 Running
- **Running**: 2101, 2201, 2303, 2304, 2305, 2306, 2307, 2308, 2401, 2402, 2403
- **Stopped**: 2301 (pre-start hook error - requires investigation)

### Peer Connections: Healthy ✅
- Most nodes have 7+ peer connections
- Total peer connections: 60+

---

## Issues Fixed

### 1. Permissions File Location ✅
**Problem**: Besu config pointed to `/permissions/permissions-nodes.toml` but file was at `/etc/besu/permissions-nodes.toml`

**Solution**: Copied permissions file to `/permissions/` directory on all nodes

### 2. Static Nodes File Location (2403) ✅
**Problem**: VMID 2403 config pointed to `/genesis/static-nodes.json`

**Solution**: Copied static-nodes.json to `/genesis/` directory

### 3. Port Conflict (2403) ✅
**Problem**: Node.js process using port 9545 (metrics port)

**Solution**: Disabled metrics for VMID 2403 (`metrics-enabled=false`)

---

## Remaining Issue

### Container 2301 Startup Error
**Status**: Not fixed (requires separate investigation)

**Error**: `lxc_init: 845 Failed to run lxc.hook.pre-start`

**Impact**: 1/12 containers unavailable

**Recommendation**: Investigate pre-start hook or recreate container

## Block Synchronization

**Current State**:
- 8 nodes at block 1,145,367 (synced group 1)
- 2 nodes at block 1,149,992 (synced group 2)
- 1 node at block 600,172 (syncing - VMID 2403)

**Note**: VMID 2403 is syncing from an older state. It will catch up over time.

  curl -s -X POST -H "Content-Type: application/json" \
    --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
    http://$ip:8545 | grep -q "result" && echo "✓ $ip" || echo "✗ $ip"
done
