Hello,

I have a large raw disk I backup to a usb disk mounted. The backup failed as I hadn't cleaned up the old backup first which tends to happen a few times a month. The failure happens when the disk runs out of space. Typically once it fails the used temp space is cleaned up and the inodes are freed. I delete an old backup and start it again. No issues.

This time the backup failed, the mount broke so I had to reboot the box. I get back into the OS, the disk shows full. The inodes are 100% in use but there are only 600GB of files on a 8GTB disk.

/dev/sdh2 7813894144 7811710976 2183168 100%

Where does proxmox write temp data during the backup process? I can't seem to find anything eating these inodes.
 
File system version 1.0
Sector size 512 bytes
Cluster size 2 MB
Volume size 7452 GB
Used space 7450 GB
Available space 2138 MB
Totally 9 directories and 32 files.

The mount doesn't add up to this at all...

DU shows the root of the mount using most of the space... there are no visible files.

Backed up my backups (lol) and created a new filesystem for the disk to resolve.

Not sure why but my disk was formatted with exfat which isn't really a good choice.
