I'm still using Red Hat's suite, but I am now in the process of learning 
pacemaker in anticipation of RHEL 7. Unfortunately, I have no tutorial 
for pacemaker (yet, I am working on one).

The tutorial I can best recommend is this;


As a side note;

OpenAIS was deprecated in favour of corosync, which is really just the 
cluster-stuff from OpenAIS stripped out (openais is now a plug-in to 
corosync for people who want/need the full AIS API).

If you are on RHEL 6 (or CentOS, etc), then you will want corosync + 
pacemaker + cman plugin, as I've been told. If you are using corosync 
v2+, then you don't need cman because corosync itself is a quorum 
provider in v2+ (corosync 1.4 is used in RHEL 6, so cman is needed as 
the quorum provider).

Hope this helps. :)


ps - #linux-cluster and #linux-ha are active on freenode. feel free to 
stop by and say hi.
