Hi Vincenzo,

 

your solution is much more better, so thank you very much for your notes. I will try that too!

Hi

 

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.

I know, that Sašo did a great job about that on his blog http://zfs-create.blogspot.cz but I never found the way, how to successfully configure that on current OmniOS versions.

 

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. 

Is there anyone, who tried that before? Any eperience with that?

 

Thank you,

 

Filip Marvan

 

 




Hi Filip,

 

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: http://blog.zhaw.ch/icclab/use-pacemaker-and-corosync-on-illumos-omnios-to-run-a-ha-activepassive-cluster/, maybe it can be useful for you.

 

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!).

If this way is worth it, rather than a quicker and more custom solution, depends on the long term plans :).

 

Best regards,

Vincenzo.
