Overview
|
|
--------
|
|
The ``ceph-volume`` tool aims to be a single purpose command line tool to deploy
|
|
logical volumes as OSDs, trying to maintain a similar API to ``ceph-disk`` when
|
|
preparing, activating, and creating OSDs.
|
|
|
|
It deviates from ``ceph-disk`` by not interacting or relying on the udev rules
|
|
that come installed for Ceph. These rules allow automatic detection of
|
|
previously setup devices that are in turn fed into ``ceph-disk`` to activate
|
|
them.
|
|
|
|
|
|
``ceph-volume lvm``
|
|
-------------------
|
|
By making use of :term:`LVM tags`, the :ref:`ceph-volume-lvm` sub-command is
|
|
able to store and later re-discover and query devices associated with OSDs so
|
|
that they can later activated.
