-This subcommand facilitates the setup of :term:`filestore` or
-:term:`bluestore`. Before you run ``ceph-volume lvm prepare``, we recommend

``prepare`` adds metadata to logical volumes but does not alter them in any

``prepare`` uses :term:`LVM tags` to assign several pieces of metadata to a
logical volume. Volumes tagged in this way are easier to identify and easier to

-play in the Ceph cluster (for example: journal, filestore, or bluestore).
