<p class="MsoNormal"

few guys before, I'm thinking again about High

great commercial RSF-1, but that's quite expensive
for my needs.<o:p></o:p></p>

<p class="MsoNormal"

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. <o:p></o:p></p>

<p class="MsoNormal">I am not directly answering your
question, but I've gone through the configuration of HA
(with pacemaker) on OmniOS in the past months and
collected all my notes here: <a moz-do-not-send="true"

<p class="MsoNormal">In my experience, running pacemaker
correctly on OmniOS is just the tip of the iceberg, then
comes the implementation/configuration of the resource
agents (and the cluster itself!).<o:p></o:p></p>

a quicker and more custom solution, depends on the long

Have you looked at the setup that Saso Kiselkov describes in his
blog here:
<a class="moz-txt-link-freetext" href="http://zfs-create.blogspot.nl/2013/06/building-zfs-storage-appliance-part-1.html">http://zfs-create.blogspot.nl/2013/06/building-zfs-storage-appliance-part-1.html</a><br>
It seems to cover most of a pacemaker setup, including the resource
agents.<br>
<br>
