## Execution Instructions

### When Nodes Are Accessible

1. **Verify Node Connectivity:**
   ```bash
   ping -c 2 192.168.11.10  # ml110
   ping -c 2 192.168.11.12  # r630-02
   ```

2. **Execute Complete Migration Script:**
   ```bash
   cd /home/intlc/projects/proxmox
   ./scripts/complete-all-remaining-migrations.sh
   ```

3. **Monitor Progress:**
   - Watch log output in real-time
   - Check log file: `reports/status/complete_migrations_*.log`
   - Verify each container migration step

4. **Verify Completion:**
   ```bash
   # Check container distribution
   ssh root@192.168.11.10 "pct list | wc -l"
   ssh root@192.168.11.12 "pct list | wc -l"
   
   # Check CPU usage
   ssh root@192.168.11.10 "top -bn1 | grep Cpu"
   ssh root@192.168.11.12 "top -bn1 | grep Cpu"
   
   # Check thin2 storage
   ssh root@192.168.11.12 "pvesm status | grep thin2"
   ```

## Migration Method Details

### Backup/Restore Process

For each container:
1. **Backup:** Create backup to `local` storage on source node
   - Command: `vzdump <vmid> --storage local --compress gzip --mode stop`
   - Time: ~5-10 minutes per container

2. **Transfer:** Copy backup file to target node
   - Method: SCP transfer
   - Time: ~1-2 minutes per container

3. **Destroy:** Remove container from source node
   - Command: `pct destroy <vmid> --force`
   - Required before restore

4. **Restore:** Restore container on target with new storage
   - Command: `pct restore <vmid> <backup-file> --storage <target-storage>`
   - Time: ~5-10 minutes per container

5. **Start:** Start container on target node
   - Command: `pct start <vmid>`
   - Verify: Check container status

**Total Time per Container:** ~10-15 minutes

- ✅ **14 containers migrated** (7 completed, 7 pending)
- ✅ **thin2 capacity reduced** from 88.86% to <50%
- ✅ **Optimal resource distribution** across all nodes
- ✅ **All nodes balanced** at 15-20% CPU usage

---

## Troubleshooting

### If Migration Fails

1. **Check Node Connectivity:**
   ```bash
   ping -c 2 <node-ip>
   ssh root@<node-ip> "uptime"
   ```

2. **Check Storage Space:**
   ```bash
   ssh root@<node> "df -h /var/lib/vz"
   ssh root@<node> "pvesm status"
   ```

3. **Check Container Status:**
   ```bash
   ssh root@<node> "pct list"
   ssh root@<node> "pct status <vmid>"
   ```

4. **Review Logs:**
   ```bash
   tail -f reports/status/complete_migrations_*.log
   ```

### Common Issues

1. **Storage Full:** Ensure `local` storage has space for backups
2. **Container Running:** Script stops containers automatically
3. **Network Issues:** Check connectivity before running
4. **Storage Mismatch:** Script handles this via backup/restore
