Try the following steps:

1) disable iptables
2) add <logging debug="on"/> before <clusternodes>
3) try to start the cluster with: "/etc/init.d/cman start join"

if it still fails, then please collect all the logs from /var/log/cluster.

Point 3 is to break the init script at cman startup time. There is no
point to load everything else if cman doesn´t work.

If the cluster starts, then verify with "cman_tool status" and
"cman_tool nodes" that the nodes can see each other and then you can
simply execute again "service cman start" to start all the other cluster
components.
