Yes, storage is ZFS, and 'Thin provision' is enabled.

VM is an RH8, so pretty new, so have full support for discard. And, as just
stated, trimming effectively free some TB of data, but not what we expect...

Effectively the VM use LVM, but looking around seems to me that discard is
'transparent' against LVM, eg, there's no need/way to 'enable' or 'disable'
it... if it is supported by the underlying storage...
