<p class="MsoNormal">Hi<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<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.<u></u><u></u></p>
<p class="MsoNormal">I know, that Sašo did a great job about that on his blog <a href="http://zfs-create.blogspot.cz" target="_blank">http://zfs-create.blogspot.cz</a> but I never found the way, how to successfully configure that on current OmniOS versions.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></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.
<u></u><u></u></p>
<p class="MsoNormal">Is there anyone, who tried that before? Any eperience with that?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
