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

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

Migrating
|
|
---------
|
|
Starting on Ceph version 12.2.2, ``ceph-disk`` is deprecated. Deprecation
|
|
warnings will show up that will link to this page. It is strongly suggested
|
|
that users start consuming ``ceph-volume``. There are two paths for migrating:
|
|
|
|
#. Keep OSDs deployed with ``ceph-disk``: The :ref:`ceph-volume-simple` command
|
|
provides a way to take over the management while disabling ``ceph-disk``
|
|
triggers.
|
|
#. Redeploy existing OSDs with ``ceph-volume``: This is covered in depth on
|
|
:ref:`rados-replacing-an-osd`
|
|
|
|
New deployments
|
|
^^^^^^^^^^^^^^^
|
|
For new deployments, :ref:`ceph-volume-lvm` is recommended, it can use any
|
|
logical volume as input for data OSDs, or it can setup a minimal/naive logical
|
|
volume from a device.
|
|
|
|
Existing OSDs
|
|
^^^^^^^^^^^^^
|
|
If the cluster has OSDs that were provisioned with ``ceph-disk``, then
|
|
``ceph-volume`` can take over the management of these with
|
|
:ref:`ceph-volume-simple`. A scan is done on the data device or OSD directory,
|
|
and ``ceph-disk`` is fully disabled. Encryption is fully supported.
