[Pacemaker] Notes on pacemaker installation on OmniOS

Fri Nov 14 08:40:33 UTC 2014

I am very happy that I somehow triggered this discussion :).

What I did was basically just take the information that was available to me
(thanks to Andreas notes and mainly his previous patches that he sent over
the years) and provide a single place where one could look at and get
pacemaker running on OmniOS.

When I started this work I was a complete newbie on Illumos and pacemaker,
so I realized that I would have saved a lot of time if some tutorial like
that existed.
Unfortunately, I couldn't have too much of a critical eye, as a beginner,
so I ignored some things, like trying to run pacemaker compiled with the
latest sources as root instead of hacluster (this was my first attempt,
with old sources, and failed, so I didn't change the script again later).

So, I just tried to use root as "CLUSTER_USER" in the SMF script and the
cluster seems to run correctly, so I will update this in the post.
