Proxmox Backup Server - No space left on device
I was recently greeted with backup failures, from what appeared to be a full disk.
102: 2026-01-22 06:00:08 ERROR: Backup of VM 102 failed - VM 102 qmp command 'backup' failed - backup connect failed: command error: mkstemp "/var/log/proxmox-backup/tasks/AF/UPID:pbs:000002CC:000004AF:00000396:69721148:backup:Unraid\\x2dMain\\x3avm-102:root@pbs:.tmp_XXXXXX" failed: ENOSPC: No space left on device
As, it turns out, this is an inode issue and not a full mount point.
