Re: [Linux-cluster] How to disable node?

You have to give your cluster 2 node setting on remaining two nodes.

How can I define a two-node cluster if a majority is needed to reach quorum?

We had to allow two-node clusters, so we made a special exception to the quorum rules. There is a special setting "two_node" in the /etc/cluster.conf file that looks like this:

<cman expected_votes="1" two_node="1"/>
This will allow one node to be considered enough to establish a quorum. Note that if you configure a quorum disk/partition, you don't want two_node="1".
