Hi,
I have a problem with my cluster and quorum settings and any help will
be appreciated.
I have a five node cluster with quorum vote of 1 for all the 5 nodes.
They have a GFS shared file system on all the five nodes, and, two
domains and two services involving two nodes.
When I shut down the 3 nodes that don't participate in the two domains
and clustered services, both the services stop and fail to start when
tried manually also.
I guess it is something to do with the quorum settings, but not sure
on the way forward.
The environment is on RHEL AS 4U2 with GFS 6.1 and RHCS 4U2.
Regards,
Kumaresh

If you have 3 nodes of 5 falling down, your cluster becomes a two node
cluster.
So, as it is written in documentation, it's a "special cluster" and it
has to be specified (in cluster.conf or by this command "can_tool join -2")
When you have a two node cluster, it is possible that each node is
isolated (this is the "splitbrain" ).
