      and must match the corresponding value defined in CephExternalMultiConfig.
        CephClusterName (must match the CephExternalMultiConfig entry's 'cluster')
        CephClusterFSID (must match the CephExternalMultiConfig entry's 'fsid')
      The following parameters are optional, and override the corresponding
      parameter's default value.
