Oh, it seems I just somehow missed the "zfs" part yesterday (local) morning..

As we already have the base support for the other target providers it can
make sense to at least evaluate this and if no show-stoppers come up also
integrate it into PVE.

Can you please open a enhancement request over at:
https://bugzilla.proxmox.com/

Some more details regarding your SAN would be also nice to have in that
request, if possible.

cheers,
Thomas
