+**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.
+
+The lvs associated with the OSD need to have been prepared previously by
+ceph-volume so that all needed tags and metadata exist.
+
+Usage::
+
+ ceph-volume lvm list
+
+List a particular device, reporting all metadata about it::
+
+ ceph-volume lvm list /dev/sda1
+
+List a logical volume, along with all its metadata (vg is a volume
+group, and lv the logical volume name)::
+
+ ceph-volume lvm list {vg/lv}
+
+Positional arguments:
+
+* <DEVICE> Either in the form of ``vg/lv`` for logical volumes or
+ ``/path/to/sda1`` for regular devices.
+
+
+**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 filesystems present
+on the given lv or partition will be removed and all data will be purged.
+
+However, the lv or partition will be kept intact.
+
+Usage, for logical volumes::
+
+ ceph-volume lvm zap {vg/lv}
+
+Usage, for logical partitions::
+
+ ceph-volume lvm zap /dev/sdc1
+
+Positional arguments:
+
+* <DEVICE> Either in the form of ``vg/lv`` for logical volumes or
+ ``/path/to/sda1`` for regular devices.
+
+
+simple
+------
+
+Scan legacy OSD directories or data devices that may have been created by
+ceph-disk, or manually.
+
+Subcommands:
+
+**activate**
+Enables a systemd unit that persists the OSD ID and its UUID (also called
+``fsid`` in Ceph CLI tools), so that at boot time it can understand what OSD is
+enabled and needs to be mounted, while reading information that was previously
+created and persisted at ``/etc/ceph/osd/`` in JSON format.
+
+Usage::
+
+ ceph-volume simple activate --bluestore <osd id> <osd fsid>
+
+Optional Arguments:
+
+* [-h, --help] show the help message and exit
+* [--bluestore] bluestore objectstore (default)
+* [--filestore] filestore objectstore
+
+Note: It requires a matching JSON file with the following format::
+
+ /etc/ceph/osd/<osd id>-<osd fsid>.json
+
+
+**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
+directory as well.
+
+Optionally, the JSON blob can be sent to stdout for further inspection.
+
+Usage on data devices::
+
+ ceph-volume simple scan <data device>
+
+Running OSD directories::
+
+ ceph-volume simple scan <path to osd dir>
+
+
+Optional arguments:
+
+* [-h, --help] show the help message and exit
+* [--stdout] Send the JSON blob to stdout
+* [--force] If the JSON file exists at destination, overwrite it
+
+Required Positional arguments:
+
+* <DATA DEVICE or OSD DIR> Actual data partition or a path to the running OSD
+
+**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.
+
+Usage::
+
+ ceph-volume simple trigger <SYSTEMD-DATA>
+
+The systemd "data" is expected to be in the format of::
+
+ <OSD ID>-<OSD UUID>
+
+The JSON file associated with the OSD need to have been persisted previously by
+a scan (or manually), so that all needed metadata can be used.
+
+Positional arguments:
+
+* <SYSTEMD_DATA> Data from a systemd unit containing ID and UUID of the OSD.
