I suspect that a quorum<br>disk is not necessary, though if you have a SAN anyway, I wouldn't argue<br>against using it. Unless you need the heuristics though, it's probably<br>not needed. You can safely build a 2-node cluster, you just need to make<br>sure your fence devices work (which is needed, regardless).<br><br>I have a tutorial that shows how to implement a cluster using cman,<br>clvmd and other components.
