[PVE-User] ZFS/PVE5 and fstrim...

[Marco Gaiarin]

I'm used, on PVE 4.4, to enable fstrim also for containers. I've setup
a simple script:

***@vdctms1:~# cat /etc/cron.weekly/dofstrim
#!/bin/ sh
for mount in /; do
fstrim $mount
done

but:

***@vdctms1:~# fstrim -v /
fstrim: /: the discard operation is not supported

it is PVE5 or ZFS that have no support for fstrim on containers? Seems
that on VM fstrim works (same phisical server):

***@vdmtms1:~# fstrim -v /
/: 5,9 MiB (6168576 bytes) trimmed

Thanks.
