8.2.2. Configuring CMAN

The first thing we need to do, is tell CMAN complete starting up even without quorum. We can do this by changing the quorum timeout setting:

[root@pcmk-1 ~]# sed -i.sed "s/.*CMAN_QUORUM_TIMEOUT=.*/CMAN_QUORUM_TIMEOUT=0/g" /etc/sysconfig/cman

Next we create a basic configuration file and place is in /etc/cluster/cluster.conf. The name used for each clusternode should correspond to that node's uname -n, just as Pacemaker expects. The nodeid can be any positive mumber but nust be unique.

Example 8.1. Basic cluster.conf for a two-node cluster

	
<?xml version="1.0"?>
<cluster config_version="1" name="my_cluster_name">
  <logging debug="off"/>
  <clusternodes>
    <clusternode name="pcmk-1" nodeid="1"/>
    <clusternode name="pcmk-2" nodeid="2"/>
  </clusternodes>
</cluster>
