I doubt that. We are backing up to Ceph (cephfs) and there are still 8
TB free ;-)

Sounds like a disk space issue. You're running out of it during the

Dear all,
on our PVE cluster, the backup of a specific VM always fails (which
makes us worry, as it is our GitLab instance). The general backup
plan is "back up all VMs at 00:30". In the confirmation email we see,
that the backup of this specific VM takes six to seven hours and then
fails. The error message in the overview table used to be:
vma_queue_write: write error - Broken pipe

The VM has some quite big vdisks (20G, 1T and 2T). All stored in
Ceph. There is still plenty of space in Ceph.
Can anyone give us some hint on how to investigate and debug this
further?
Thanks in advance
Frank
