[Linux-cluster] Cannot join two nodes together

[Ozarchuk, John D]

This is a cman_tool nodes from each node...

[root at bplmft11 ~]# cman_tool nodes
Node  Sts   Inc   Joined               Name
   1   X     24                        bplmft12
   2   M      4   2007-09-26 13:33:04  bplmft11

[root at bplmft12 ~]# cman_tool nodes
Node  Sts   Inc   Joined               Name
   1   M      4   2007-09-26 14:35:16  bplmft12
   2   X     24                        bplmft11

It's as if each node is locally joined but the other node is not.

You probably want to set the "two_node=1" option in the cluster.conf 
file. A good explanation of the caveats of a two-node cluster can be 
found in the FAQ, found here:
