Michael,

The problems had to do with node membership (a node joining
the cluster twice with different names) and a bug that caused
pengine to die periodically. For now I am just running the 
clusters in maintenance mode (unmanaged) as I think Pacemaker
1.0.x is too old for my use case. 

I would recommend using Corosync 2.x with Pacemaker so that you 
can obtain membership and quorum data from the same source for 
all parts of the stack (#3 on this page):

Thanks,

Andrew
