Aktuell können wir keine Backups mehr von einem CT machen. Die Disk ist mit ca. 800GB recht groß. Aber das Storage und der Backupserver haben mehr als genug freien Platz. Testweise wurde auch ein NFS Storage angebunden, aber dorthin kommt der selbe Fehler. Es scheint also irgendwie am Linstor DRBD zu liegen.

Das DRBD liegt auf einem ZFS Raid 1.

I don't think the issue is on the target/backup side, but on the "source". For backups to work, I think PVE needs an actual resource/block device it can create the backup from. Also IIRC, the plugin creates a LINSTOR snapshot, which creates snapshots on the actual devices, then the plugin is asked to create a new resource from that snapshot (this is where you run out of space), then PVE does its magic and calls into the plugin to delete the temporary resource + the LINSTOR snapshot.

We did an upgrade to proxmox 8 and we deleted old snapshots/linstor resource-definitions...
