Firewall is off. I can do a ccsd, cman_tool join, cman_tool nodes and get
info. However, looking in the logs shows that the systems don't even see
each other.
[root@sleepy ~]# cman_tool nodes
Node Sts Inc Joined Name
1 M 4 2007-05-07 15:47:35 sleepy
2 X 0 sleepy2
The systems try to fence each other right away.
May 7 14:28:12 sleepy fenced[2655]: fencing node "sleepy2"
May 7 14:28:12 sleepy fence_manual: Node sleepy2 needs to be reset before
recovery can procede. Waiting for sleepy2 to rejoin the cluster or for
manual acknowledgement that it has been reset (i.e. fence_ack_manual -n
sleepy2)

Output from /var/log/messages would be helpful. If you configure a
firewall by default, you must add a firewall rule for port 5405 UDP to
allow connections from other cluster nodes. This is most likely the
problem you are having.
