You have to give your cluster 2 node setting on remaining two nodes. <h4 id="head-200e385dd3c1cfc014b936b76753151e8b2a707f">How can I define a two-node cluster if a majority is needed to reach quorum?</h4> 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: <pre> <cman expected_votes="1" two_node="1"/></pre>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". <a href="http://sources.redhat.com/cluster/wiki/FAQ/CMAN#two_node">http://sources.redhat.com/cluster/wiki/FAQ/CMAN#two_node</a> <div class="gmail_quote">On Mon, Aug 31, 2009 at 3:30 PM, Jakov Sosic <<a href="mailto:jakov.sosic@srce.hr">jakov.sosic@srce.hr</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi. I have a problem that one of my 3 nodes is sent to RMA to hardware dealer. I want to know is it possible to disable that one node, because clurgmgrd is not starting any services because cman is unable to fence the missing node...
