I'm copying the users list so that others can benefit from this discussion.

What is the output of the "hostname" command on the system called
"cluster_2".
What is the output of the command:

nslookup `hostname`

when you run it on cluster_2?

The nslookup command must succeed in order for the GF server to start.

Command failed on node 2 (cluster_2): CLI801 Instance is already synchronized There is a process already using the admin port 24848 -- it probably is another instance of a GlassFish server. Command start-local-instance failed. To complete this operation run the following command locally on host cluster_2 from the GlassFish install location /APP/glassfish3: asadmin start-local-instance --node 2 --sync normal inst-2 The command start-instance executed successfully for: inst-1 The command start-instance failed for: inst-2
