[PVE-User] pve wiki docs wrong -- shared zfs via iscsi isn't possible

so, if it's like you tell, why is LVM-thin set to "no" ?

with that paradigm every ordinary filesystem or volume management on top
of SAN storage could be "shared", as long it's not actively being used
by multiple nodes at the same time.

we could for example have BTRFS over iscsi or EXT4 via ISCSI - so why
only ZFS via ISCSI ?

i would say "shared" needs some better explanation/definition here, as
we see it leaves room for speculation
