It does seem to be a zfs version issue which kinda makes sense. If I
create the zfs image on a RELENG10 vm it works.=C2=A0 The only issue is t=
hat
its quite slow to do on the VM as its a LOT of disk IO.=C2=A0 Is there a =
way
to create an older version of a zfs file system on a newer version of
FreeBSD so I can get the best of both worlds ?
