[SOLVED] Local (pve) unknown storage (VE 8.0)

I have an issue where my local (pve) storage is showing 84/100 GB data being used but I can't find where this space is being used up and I'd like to open up some more space.

The proxmox OS is on the local (pve), along with some ISOs that should only take around 11 GB.


When I run df -h, the system is showing /dev/mapper/pve-root with 78G mounted on / which seems way high.

When I run ncdu I see the following.. /dev/mapper is taking up basically nothing.

I also checked out /var/lib/vz which is the path that local is pointed to:
ncdu shows 9.8GB being used, following the /template/iso contains my ISOs as expected and wouldn't be anything I'd want to delete.

So is there something wrong with configuration, or is there some hidden files I'm not seeing to go delete?

My largest data I can find is on /mnt (my USB Backup), these are storing VM backups - so I still have about 71GB unaccounted.

Any help would be appreciated, thanks!

what is the output of: du -h -x -d1 /

Your usb is in /mnt/USB_backup , is there anything in /mnt besides that folder?

Also, unmount the USB disk - do you find anything in that folder still? If you written to the location while the disk was not mounted, it landed on root disk but will not be immediately seen.
