Backup error on stopped VM (KVM)

[bazzi]

Ok tonight we had a backup error on a VM (KVM) that has a disk on LVM-VM-Disks (Proxmox name of a vg called vmdisk). Also when we try to run a backup from the VM backup tab we will get this error:

Backup error:

INFO: ionice priority: 7
ERROR: Backup of VM 203 failed - no such volume 'LVM-VM-Disks:vm-203-disk-1'

So if you can see the disk is there, so we don't know how to fix it. On other VM's that are stopped (these are on other nodes) the backup is working. Also if we run the VM we can backup. But if it is stopped we will get that error.

Please can you post your storage configuration?

# cat /etc/pve/storage.cfg

Owwh and I just updated 4 packages, but he problem still exists
