Thanks for your reply. Our two servers are donuts (server1) and coffee (server2) have been configured with CMAN but the outcome isn’t quite what we expect. On donuts a 'clustat' gives us some errors.
[root donuts ~]# clustat

My cluster.conf file reads as following on this machine.
[root donuts ~]# cat /etc/cluster/cluster.conf
<cluster alias="ngsCluster" config_version="7" name="ngs">
<fence_daemon post_fail_delay="0" post_join_delay="3"/>
<clusternode name="coffee.microslu.washington.edu" nodeid="1" votes="1">
<clusternode name="donuts.microslu.washington.edu" nodeid="2" votes="1">
However, when I try to do the same on coffee, I am unable to start cman. I've copied donuts cluster.conf file to this machine but gets overwritten with a cluster.conf file that just has 'donuts' in it every time I try to restart CMAN.
[root coffee cluster]# clustat

Make sure CMAN is running on all nodes, and all nodes have successfully joined the cluster.
