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 :).
