Hi,
Just tried a
So looks like doing a TRIM inside a unprivileged LXC isn't working. So do I need to setup discard/fstrim at all inside my LXC guestx or will PVE do a fstrim for all LXCs datasets on host level?
All my LXCs are ZFS datasets on a thin-provisioned ZFS SSD pool or LVs on a thin-provisioned LVM-thin so some kind of TRIM/discard should be required.

Looks like a

The LXC that isn't working is using a LVM-thin, the one where its working is stored on a ZFS pool.

fstrim -a is working on another unprivileged LXC. So can someone point me in the right direction why it isn't working with my other LXC?Edit:
