The standard Pacemaker config file will continue to be used for resource management even after we start using CMAN. There is no need to recreate all your resources and constraints to the cluster.conf syntax, we simply create a minimal version that lists the nodes.
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:
Next we create a basic configuration file and place it 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 must be unique.
