+ceph-volume
+===========
+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.
+
+:ref:`Overview <ceph-volume-overview>` |
+:ref:`Plugin Guide <ceph-volume-plugins>` |
+
+
+**Command Line Subcommands**
+
+There is currently support for ``lvm``, and plain disks (with GPT partitions)
+that may have been deployed with ``ceph-disk``.
+
+``zfs`` support is available for running a FreeBSD cluster.
+
+* :ref:`ceph-volume-lvm`
+* :ref:`ceph-volume-simple`
+* :ref:`ceph-volume-zfs`
+
+**Node inventory**
+
+The :ref:`ceph-volume-inventory` subcommand provides information and metadata
+about a nodes physical disk inventory.
+
+
+Migrating
+---------
+Starting on Ceph version 13.0.0, ``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`
+
+For details on why ``ceph-disk`` was removed please see the :ref:`Why was
+ceph-disk replaced? <ceph-disk-replaced>` section.
+
+
+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.
