Operational Procedures

  • Check host and guest state: pveversion && qm list && pct list.
  • Check storage: pvesm status.
  • Check disks: lsblk -o NAME,SIZE,MODEL,SERIAL,FSTYPE,MOUNTPOINTS.
  • Before shutdown, gracefully stop application guests and confirm the firewall outage window.
  • After boot, verify the documented guest startup order.

Troubleshooting

  • No management access: check vmbr0.2, the switch port, and OPNsense DMZ routing.
  • Guest disks unavailable: run pvesm status; only local and local-lvm were active on 2026-07-17. Treat older NAS storage names as historical until storage is reattached and verified.
  • Broad service outage: confirm VM 100 and CTs 101 through 106 are in their expected states.
