Why do my changes to cluster.conf file keep disappearing?
The cluster configuration system (ccs) tries to manage the cluster.conf file and keep all the nodes in sync. If you make changes to the cluster.conf file, you have to tell ccs and cman that you did it, so they can update the other nodes. If you don’t, your changes are likely to be overwritten with an older version of the cluster.conf file from a different node. See the next question.
