Thank you for the response.  /var/log/messages doesn't have any
errors.  It says cman started then says can't connect to cluster
infrastructure after a few seconds.  My cluster does not have the
two_node=1 config now.  Conga took that out for me.  That bit me last
night because I needed to put that back in.
