InstallCephWithQuattor

Overview

Prior to the installation, you must assign the roles to the machines of the cluster. The possible roles are : MON, MDS, OSD. You need at least one MON machine, but to avoid bottlenecks when the number of OSD increases, it's better to have 3 MON machines (always have an odd number of MON machines to be able to have a quorum). The MDS is only needed if you want to use CephFS.
