How to re create Red Hat Cluster with Luci web based tool

Error message:

The error displayed is something like this:

"node1 already a member of cluster1"

 

Cause

Your first attempt to create a red hat cluster fails. You end up with few missing nodes in the cluster and only few of the nodes showing in the cluster.

The reason cluster creation fails may be because of misconfigured YUM repository, wrong ricci password or ssh not running etc. Check out then proceed as told below to re create your cluster. Because of this you can't re create the cluster because few nodes are already added and this causes this error.

Solving it! - already a cluster member error

 

Delete /etc/cluster/cluster.conf (from all nodes)

You have to delete above file from all cluster nodes. In some nodes this may not be present and that's fine because it will be created later.

After you delete cluster.conf you can proceed to create a new cluster by again specifying all nodes afresh in the Luci web interface.

Here's a screen shot of a running cluster in the Luci web tool:

Enjoy! This will save lots of headache I believe. :)D
