Hello,
I wonder how the datastore usage is calculated. As far as I could find information it should be the fs size.
Code:
root@PBS:~# df -hT /mnt/datastore/TrueNAS-HDD
Filesystem Type Size Used Avail Use% Mounted on
/dev/sdb xfs 12T 476G 12T 4% /mnt/datastore/TrueNAS-HDDCode:
root@PBS:~# du -sh /mnt/datastore/TrueNAS-HDD
241G /mnt/datastore/TrueNAS-HDDSo I'd guess PBS would report a usage of 476G. But it tells me
while GC reports
Code:

2026-06-14T08:18:20+02:00: TASK OK/dev/sdb is a iscsi netdrive xfs formated. It is a zvol on truenas.
So why is PBS telling me a usage of 510.99GB??
