[PVE-User] Backup fail with 'no disk', but manually works!

[Marco Gaiarin]

I've setup a script, for a bacula backup setup, that weekly dump VMs/LXCs,
cleanup the backup dir anche then put VMs on tape.

A backup of a VM fail, every week, with:

 108: 2019-02-08 20:19:04 INFO: Starting Backup of VM 108 (qemu)
 108: 2019-02-08 20:19:04 INFO: status = running
 108: 2019-02-08 20:19:28 INFO: update VM 108: -lock backup
 108: 2019-02-08 20:19:28 INFO: VM Name: dixie
 108: 2019-02-08 20:19:28 INFO: include disk 'virtio0' 'VM0:vm-108-disk-1' 100G
 108: 2019-02-08 20:20:12 ERROR: Backup of VM 108 failed - no such volume 'VM0:vm-108-disk-1'

note that:

a) disk exist; disk reside on the same SAN with all my other VMs, that
 the same script backup without trouble.

b) i've also a ''normal'' PVE backup tasks that do a dump of that VMs
 every day, and works.

c) if i try a manual backup (from PVE web interface), work.


The script do simply:
	vzdump 108 -storage Backup -maxfiles 1 -remove -compress lzo -mode snapshot -quiet -mailto ced -mailnotification failure
