Hi David,

What normally is supposed to happen is that all three nodes are started 
at once.

The first two nodes should wait for the third node to join the fence 
domain before
they proceed.  The only reason the third node would be fenced is if it 
hasn't
reported in before the post_join_delay time specified in the 
cluster.conf file.  See:

http://sources.redhat.com/cluster/faq.html#fence_startup

I think the goal was to get the cluster in a known good fully-functional 
state
at startup.
