Re: [Linux-cluster] How to run same service in parallel in RedHat Cluster 5.0



Ok, that *looks* fine. So when you start the cman and rgmanager, what
does 'clustat' show?

Also, *setup fencing*. Without fencing configured, weird things will
happen. Once you have fencing configured and tested, paste the updated
cluster.conf and the output of clustat.
