Proxmox. ERROR: Backup of VM 109 failed – CT is locked (backup)
  • I try to create backup of the container (LXC) in my Proxmox and I get the error:
INFO: starting new backup job: vzdump 109 --node myserver --mode snapshot --storage backups-stor --remove 0 --compress lzo
INFO: Starting Backup of VM 109 (lxc)
INFO: status = running
ERROR: Backup of VM 109 failed - CT is locked (backup)
INFO: Backup job finished with errors
TASK ERROR: job errors
  • I get error message:
Configuration file 'nodes/myserver/qemu-server/109.conf' does not exist

Bug fix

KVM:

qm unlock <VM ID>
qm unlock 109

LXC

pct unlock <ID>

in my case:

pct unlock 109
