The ups-shutdown-cluster.sh script was missing LXC container shutdown
functionality, only shutting down VMs. This could leave containers
running during UPS power failure, causing ungraceful shutdown.
Changes:
- Added Step 2: LXC container shutdown on all cluster nodes
- Uses 'pct list' to find running containers
- Shuts down each container with 60s timeout
- Parallel shutdown with '&' for speed
- Both local (pvemini) and remote nodes (pve1, pveelite)
- Updated step numbers (now 6 steps total vs 5 before)
- Fixed log_message() to use dynamic timestamp
- Fixed node name comment (pve2 → pveelite)
Shutdown order:
1. VMs on all nodes (timeout 60s)
2. LXC containers on all nodes (timeout 60s) [NEW]
3. Wait 90 seconds for graceful shutdown
4. Secondary nodes shutdown (pve1, pveelite)
5. Wait 30 seconds
6. Primary node shutdown (pvemini)
This matches the behavior in ups-maintenance-shutdown.sh which already
had LXC support.
