[PVE-User] zfs 0.7 no discard

Hi All,

Currently having an issue on a few servers where more space is being "used"
in the host (zfs), than is actually being used inside the VM. Discard is
enabled, but zfs 0.7 does not have support for it.

zfs 0.8 has brought in discard support, so I was wondering if anyone else
has upgraded to it to resolve this kind of issue?

I realise it's in proxmox 6, but I don't want to go there until it's out of

Any comments appreciated!
