When a cluster has been shut down and then re-started, how do the monitors know what the cluster fsid is? Is it stored somewhere? I would like to be able to verify, before starting a monitor on a given server, if an existing monitor directory belongs to the current cluster or to a previous cluster incarnation. With the OSDs, I can just check the cluster_fsid file.
