5.3. Adding Red Hat Gluster Storage Server to the Cluster

There are two ways to add hosts. You can either add new hosts or import the existing gluster configuration into a cluster.

To import an existing gluster configuration:
1. Select Enable Gluster Service.
2. Select Import existing gluster configuration. With this option you can import the existing Gluster configurations into a cluster.
3. Provide the IP address of one of the hosts.
To add new hosts:
1. Use the drop-down lists to select the Data Center and Host Cluster for the new host.
2. Click OK.
  The new host displays in the list of hosts with a status of Installing. The host is activated and the status changes to Up automatically.
You can manage the lifecycle of a volume using hook scripts.
Note
Install cockpit using # yum install cockpit, before adding the Red Hat Gluster Storage 3.5 node to Red Hat Virtualization Manager 4.3 in 4.3 compatible cluster.
Note
To add multiple servers to a cluster, you must first add a Red Hat Gluster Storage server to the cluster. An error message appears if you add multiple servers in the first attempt.
