Execution Instructions

When Nodes Are Accessible

1. Verify Node Connectivity:

   ping -c 2 192.168.11.10  # ml110
   ping -c 2 192.168.11.12  # r630-02
   

2. Execute Complete Migration Script:

   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:

   # 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

• ✅ Zero downtime for migrated containers (they restarted successfully)
• ✅ Complete hardware documentation
• ✅ Storage issues identified and documented

Expected After Completion

• ✅ 70-80% CPU reduction on ml110 (from 81.5% to 15-20%)
• ✅ 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:

   ping -c 2 <node-ip>
   ssh root@<node-ip> "uptime"
   

2. Check Storage Space:

   ssh root@<node> "df -h /var/lib/vz"
   ssh root@<node> "pvesm status"
   

3. Check Container Status:

   ssh root@<node> "pct list"
   ssh root@<node> "pct status <vmid>"
   

4. Review Logs:

   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
