Running PVE 8.1.3
Getting a strange error when running individual backups (not scheduled).
Some VMs reports a Stale file handle when the backup process runs
When I deleted the storage device (NAS-X-01) and readded it a few of the failed backups were then re-run successfully, but there are a few still that keep reporting the same problem.
There is no mount point defined in fstab, but it is defined in /proc/mounts on each node
All my scheduled backups (to another device, configured exactly the same) work as expected daily.
Looking at /mnt/pve/NAS-X-01 from the PVE servers, I can see all the completed backups from each node. The only file remaining from the failed backups is a .log file. It appears that it can't create the .dat file?
Update: I've now managed to backup all the VMs except for 2 which still both report the Stale File Handle error - and despite multiple attempts now, these two fail every time I attempt a backup.
It's obviously not a permissions problem as all the other VMs backed up OK to this device.
