As per the subject. I have VM's whose disks are thin provisioned, say 30GB
actual disk usage of a 128GB disk as qcow2 on CephFS (qcows2) and .NFS

When I move them to ZFS they become fat provisioned, taking up all the
space allocated to them (128GB, 1TB etc), regardless of content. The ZFS
STorage *sdoes* have "Thin Provisioned" ticked.

If I create a empty drive via the proxmox ui directly on the ZFS pool, it
is indeed thin provisioned, only taking up a few k.

Is there a way to work around this? its stalled my entire migration - I
don't have room on my ZFS pool to accommodate all the fat provisioned
drives, plus it would slow my backups down by a huge amount.
