9.2.4. Installing Additional Nodes

When creating a new storage node, two components are always installed: the storage node and a companion agent. The only required information to set up the node is the IP address of the JBoss ON server. The agent registers with the server and then sends the storage node hostname or IP address. The server then distributes that information among the other agents and it gets propagated into the cluster.

If the cluster is using custom client and gossip ports, then edit the rhq-storage.properties file with the correct ports before running the installation script.

Run the installation script with the --agent-preference option to supply the server bind address. For example:

serverRoot/jon-server-3.2.GA/bin/rhqctl install --storage --agent-preference="rhq.agent.server.bind-address=0.0.0.0"

[root@server ~]# serverRoot/jon-server-3.2.GA/bin/rhqctl install --storage --agent-preference="rhq.agent.server.bind-address=0.0.0.0"

The deployment operation can take several minutes to complete, as the new node information is propagated among the existing nodes. Until the deploy operation is complete, the node shows a status of Joining.
