[pve-devel] any plan for zfs over open-iscsi (linux)?

[Travis Osterman]

I think the title says it all. I use open-iscsi for my SAN and wondered
whether there was a plan to support that the way LIO and IET are supported
within Proxmox. Neither LIO or IET are available for my linux distribution
and do not seem to be actively supported.

I'm not a native perl coder but would happily be a tester for anyone
interested in this feature. If I'm alone, I may start trying to come up
with something. Thanks.

I'm only waking up so excuse if I overlook something, but what's wrong
with the non-user-mode iSCSI storage type of PVE?

That does, indeed, work fine. iSCSI over ZFS provides additional support
for quickly provisioning, snapshotting and rolling back images all through
the UI. From what I can see, proxmox connects to the NAS to issue the
commands to perform those functions. When I use the iSCSI (without ZFS), I
have access both proxmox and my NAS. Does that make sense?

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

Thanks, Thomas. I also incorrectly wrote "open-iscsi" which is my typical
iscsi client instead of "TGTD" which is my SAN target provider. I've
submitted an enhancement request, linked below.

Thanks for your consideration.
