ESOS and ZFS

[Müller]

I am currently trying to set up ZFS on ESOS. Here I got some questions before I continue further.

In general, how well does ESOS handle ZFS? Is there any known problems?

I have two storage hosts that I am trying to configure. These two I would like to go together in a cluster. Is there any problem with this, considering I am using ZFS?

Thanks.

I forgot to mention that I am planning to use ZFS with iSCSI. Are there any known problems doing this?

I'm aware of a couple others that have tried/used it. The downside
with ZFS (in my experience) is performance, at least with the
'vdisk_blockio' handler (direct I/O). You may find better luck with
ZFS doing buffered I/O on the target-side (ESOS) using the
'vdisk_fileio' handler... of course the downside with doing buffered
I/O is potentially losing writes in a power loss / crash scenario.
