Redhat HA nodes not joining


I have setup a basic 2 node Redhat cluster. The problem am having is when i run clustat from both nodes only the local node shows online the other shows as offline.


Cluster Status for cluster-1 @ Thu Jun 3 13:23:39 2014

server1 1 Offline
server2 2 Online, Local


Cluster Status for cluster-1 @ Thu Jun 4 10:54:02 2014

server2 2 Offline

They don't seem to have joined each other, because when I run:

cman_tool nodes
Node Sts Inc Joined Name
1 M 40 2014-06-05 12:07:13 server1
2 X 0 server2

cman_tool nodes
Node Sts Inc Joined Name
1 X 0 server1
2 M 8 2014-06-04 14:45:37 server2

I haven't done much configuration, I just want to get the basic cluster setup and get them to communicate with each other.
Please can anyone advice on what I have missed out.

Many thanks

Normally, when I've done this, I start with node 0, not node 1. 0 is the controller for the cluster, you don't normally interact with any of the other nodes except through node 0 ( I think redhat calls it domain0, but you probably want to ask one of the red hat experts).
Assuming nobody jumps up to correct me (which is fine if they do), I'd say re-read what your manual says about naming of the nodes.
