   4 ===========
   5 Deploy OSDs with different device technologies like lvm or physical disks using
   6 pluggable tools (:doc:`lvm/index` itself is treated like a plugin) and trying to
   7 follow a predictable, and robust way of preparing, activating, and starting OSDs.

  13 **Command Line Subcommands**
  14 There is currently support for ``lvm``, and plain disks (with GPT partitions)
  15 that may have been deployed with ``ceph-disk``.

  21 Migrating
  22 ---------
  23 Starting on Ceph version 12.2.2, ``ceph-disk`` is deprecated. Deprecation
  24 warnings will show up that will link to this page. It is strongly suggested
  25 that users start consuming ``ceph-volume``.
  26
  27 New deployments
  28 ^^^^^^^^^^^^^^^
  29 For new deployments, :ref:`ceph-volume-lvm` is recommended, it can use any
  30 logical volume as input for data OSDs, or it can setup a minimal/naive logical
  31 volume from a device.
  32
  33 Existing OSDs
  34 ^^^^^^^^^^^^^
  35 If the cluster has OSDs that were provisioned with ``ceph-disk``, then
  36 ``ceph-volume`` can take over the management of these with
  37 :ref:`ceph-volume-simple`. A scan is done on the data device or OSD directory,
  38 and ``ceph-disk`` is fully disabled. Encryption is fully supported.
