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.
