-
-LVM
-===
-The backend of ``ceph-volume lvm`` is LVM, it relies heavily on the usage of
-tags, which is a way for LVM to allow extending its volume metadata. These
-values can later be queried against devices and it is how they get discovered
-later.
-
-.. warning:: These APIs are not meant to be public, but are documented so that
-             it is clear what the tool is doing behind the scenes. Do not alter
-             any of these values.

-.. _ceph-volume-lvm-tag-api:
-
-Tag API
--------
-The process of identifying logical volumes as part of Ceph relies on applying
-tags on all volumes. It follows a naming convention for the namespace that
-looks like::
-
-    ceph.<tag name>=<tag value>
-
-All tags are prefixed by the ``ceph`` keyword do claim ownership of that
-namespace and make it easily identifiable. This is how the OSD ID would be used
-in the context of lvm tags::
-
-    ceph.osd_id=0
-
-
-.. _ceph-volume-lvm-tags:
-
-Metadata
---------
-The following describes all the metadata from Ceph OSDs that is stored on an
-LVM volume:
-
-
-``type``
---------
-Describes if the device is a an OSD or Journal, with the ability to expand to
-other types when supported (for example a lockbox)
-
-Example::
-
-    ceph.type=osd
-
-
-``cluster_fsid``
-----------------
-Example::
-
-    ceph.cluster_fsid=7146B649-AE00-4157-9F5D-1DBFF1D52C26
-
-``data_device``
----------------
-Example::
-
-    ceph.data_device=/dev/ceph/data-0
-
-``journal_device``
-------------------
-Example::
-
-    ceph.journal_device=/dev/ceph/journal-0
-
-``encrypted``
--------------
-Example for enabled encryption with ``luks``::
-
-    ceph.encrypted=luks
-
-For plain dmcrypt::
-
-    ceph.encrypted=dmcrypt
-
-For disabled encryption::
-
-    ceph.encrypted=0
-
-``osd_fsid``
-------------
-Example::
-
-    ceph.osd_fsid=88ab9018-f84b-4d62-90b4-ce7c076728ff
-
-``osd_id``
-----------
-Example::
-
-    ceph.osd_id=1
-
-``block``
----------
-Just used on :term:`bluestore` backends.
-
-Example::
-
-    ceph.block=/dev/mapper/vg-block-0
-
-``db``
-------
-Just used on :term:`bluestore` backends.
-
-Example::
-
-    ceph.db=/dev/mapper/vg-db-0
-
-``wal``
--------
-Just used on :term:`bluestore` backends.
-
-Example::
-
-    ceph.wal=/dev/mapper/vg-wal-0
-
-
-``lockbox_device``
-------------------
-Only used when encryption is enabled, to store keys in an unencrypted
-volume.
-
-Example::
-
-    ceph.lockbox_device=/dev/mapper/vg-lockbox-0
