<p class="MsoNormal">as few guys before, I'm thinking
again about High Availability storage with ZFS. I
know, that there is great commercial RSF-1, but
that's quite expensive for my needs.</p>

about that on his blog <a moz-do-not-send="true"

but I never found the way, how to successfully
configure that on current OmniOS versions.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">So I'm thinking about something
more simple. Arrange two LUNs from two OmniOS ZFS
storages in one software mirror through
fibrechannel. Arrange that mirror in client, for
example mdadm in Linux. I know, that it will have
performance affect and I will lost some ZFS
advantages, but I still can use snapshots, backups
with send/receive and some other interesting ZFS
things, so it could be usable for some projects. </p>
<p class="MsoNormal">Is there anyone, who tried that
before? Any eperience with that?</p>

<div>While this sounds technically possible, it is not HA.
Your client is the single point of failure. I would
wager that mdadm would create more availability issues
than it would be solving. <br>
<br>
</div>
<div>I run RSF-1 and HA is still hard to achieve. I don't
think I have gained any additional up-time overcoming
failures, but it definitely helps with planned
maintenance. Unfortunately, there are still too many
ways a zfs pool can fail that having a second server
connected does not help. <br>
