Gulm can only use 5 nodes in the servers list in 
cluster.ccs/cluster/lock_gulmd/servers.  This could be why you are having
difficulties.  Try trimming the list and see if that yields better results.

You may also want to make sure that your node names are uniquely
identifiable by their first 8 characters (this was a bug in version 
6.0.0-1.2 of the RPMs, but since you didn't post the version of the code you
are using, I can only offer this as a suggestion ;)

There would be failure messages to the console stating that you didn't have
enough journals if that was the problem.  

good luck
