Description
|
|
===========
|
|
|
|
:program:`ceph-disk` is a utility that can prepare and activate a disk, partition or
|
|
directory as a Ceph OSD. It is run directly or triggered by :program:`ceph-deploy`
|
|
or ``udev``. It can also be triggered by other deployment utilities like ``Chef``,
|
|
``Juju``, ``Puppet`` etc.
|
|
|
|
It actually automates the multiple steps involved in manual creation and start
|
|
of an OSD into two steps of preparing and activating the OSD by using the
|
|
subcommands ``prepare`` and ``activate``.
|
|
|
|
:program:`ceph-disk` also automates the multiple steps involved to manually stop
|
|
and destroy an OSD into two steps of deactivating and destroying the OSD by using
|
|
the subcommands ``deactivate`` and ``destroy``.
|
|
|
|
The documentation for each subcommand (prepare, activate, etc.) can be displayed
|
|
with its ``--help`` option. For instance ``ceph-disk prepare --help``.
