Why is the command `ceph mds metadata` not showing information for the active metadata server in Red Hat Ceph Storage?

Issue

• The commands ceph fs status and ceph mds metadata are not showing any information about the active metadata server ( MDS ). Some sample outputs:

  # ceph fs status
  my-filesystem - 0 clients

  The active MDS is my-filesystem.mons-2.awciqy in the above capture. Note that the VERSION field is empty for this MDS instance and for mdsfsname.mons-2.bxmomv. The command ceph mds metadata is also not showing any information for these two services.
