First off, I *strongly* recommend using RHEL6, not 5. There have been
many improvements, plus, EL6 will be supported longer.

What are you trying to do with your cluster? I suspect that a quorum
disk is not necessary, though if you have a SAN anyway, I wouldn't argue
against using it. Unless you need the heuristics though, it's probably
not needed. You can safely build a 2-node cluster, you just need to make
sure your fence devices work (which is needed, regardless).

I have a tutorial that shows how to implement a cluster using cman,
clvmd and other components. It also discusses the cluster components
from a high-level, which may help.
