[ClusterLabs] Fencing with a 3-node (1 for quorum only) cluster

[Dan Swartzendruber]

A lot of good suggestions here.  Unfortunately, my budget is tapped out 
for the near future at least (this is a home lab/soho setup).  I'm 
inclined to go with Digimer's two-node approach, with IPMI fencing.  I 
understand mobos can die and such.  In such a long-shot, manual 
intervention is fine.  So, when I get a chance, I need to remove the 
quorum node from the cluster and switch it to two_node mode.  Thanks for 
the info!
