Hi,
I have a proxmox backup server installed on the same machine as my proxmox server. I have the storage attached by NFS into the PBS, and then re-added into proxmox storage repositories as a PBS location.
My backups have been working fine. I just have now come across this error and am not sure what's causing it specifically:

Code:

ERROR: Backup of VM 100 failed - VM 100 qmp command 'backup' failed - backup register image failed: command error: unable to get shared lock - EIO: I/O error

I can see that it's a file locking issue - but unsure if this is on the NFS server (freeNAS) or in proxmox?
 
Never Mind
It was the Freenas server - it had a faulty disk.
Shut it down and removed the drive and after coming back on all is well again in the world =)
