Required arguments:
-* --data A logical group name or a path to a logical volume
+.. option:: --data
+
+ A logical group name or a path to a logical volume
For encrypting an OSD, the ``--dmcrypt`` flag must be added when preparing
(also supported in the ``create`` sub-command).
-**create**
+create
+^^^^^^
+
Wraps the two-step process to provision a new osd (calling ``prepare`` first
and then ``activate``) into a single one. The reason to prefer ``prepare`` and
then ``activate`` is to gradually introduce new OSDs into a cluster, and
with the convenience of doing it all at once. Flags and general usage are
equivalent to those of the ``prepare`` and ``activate`` subcommand.
-**trigger**
+trigger
+^^^^^^^
+
This subcommand is not meant to be used directly, and it is used by systemd so
that it proxies input to ``ceph-volume lvm activate`` by parsing the
input from systemd, detecting the UUID and ID associated with an OSD.
Positional arguments:
-* <SYSTEMD_DATA> Data from a systemd unit containing ID and UUID of the OSD.
+.. describe:: <SYSTEMD_DATA>
+
+ Data from a systemd unit containing ID and UUID of the OSD.
+
+list
+^^^^
-**list**
List devices or logical volumes associated with Ceph. An association is
determined if a device has information relating to an OSD. This is
verified by querying LVM's metadata and correlating it with devices.
Positional arguments:
-* <DEVICE> Either in the form of ``vg/lv`` for logical volumes,
- ``/path/to/sda1`` or ``/path/to/sda`` for regular devices.
+.. describe:: <DEVICE>
+
+ Either in the form of ``vg/lv`` for logical volumes,
+ ``/path/to/sda1`` or ``/path/to/sda`` for regular devices.
-**zap**
+zap
+^^^
+
Zaps the given logical volume or partition. If given a path to a logical
volume it must be in the format of vg/lv. Any file systems present
on the given lv or partition will be removed and all data will be purged.
Positional arguments:
-* <DEVICE> Either in the form of ``vg/lv`` for logical volumes,
- ``/path/to/sda1`` or ``/path/to/sda`` for regular devices.
+.. describe:: <DEVICE>
+
+ Either in the form of ``vg/lv`` for logical volumes,

-**scan**
+scan
+^^^^
+
Scan a running OSD or data device for an OSD for metadata that can later be
used to activate and manage the OSD with ceph-volume. The scan method will
create a JSON file with the required information plus anything found in the OSD

-* [--stdout] Send the JSON blob to stdout

+^^^^^^^
-**trigger**
This subcommand is not meant to be used directly, and it is used by systemd so
that it proxies input to ``ceph-volume simple activate`` by parsing the
input from systemd, detecting the UUID and ID associated with an OSD.
Positional arguments:
-* <SYSTEMD_DATA> Data from a systemd unit containing ID and UUID of the OSD.
