Synopsis
|
|
========
|
|
|
|
| **ceph-volume-systemd** *systemd instance name*
|
|
|
|
|
|
Description
|
|
===========
|
|
:program:`ceph-volume-systemd` is a systemd helper tool that receives input
|
|
from (dynamically created) systemd units so that activation of OSDs can
|
|
proceed.
|
|
|
|
It translates the input into a system call to ceph-volume for activation
|
|
purposes only.
|
|
|
|
|
|
Examples
|
|
========
|
|
Its input is the ``systemd instance name`` (represented by ``%i`` in a systemd
|
|
unit), and it should be in the following format::
|
|
|
|
<ceph-volume subcommand>-<extra metadata>
|
|
|
|
In the case of ``lvm`` a call could look like::
|
|
|
|
/usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
|
|
|
|
Which in turn will call ``ceph-volume`` in the following way::
|
|
|
|
ceph-volume lvm trigger 0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
|
|
|
|
Any other subcommand will need to have implemented a ``trigger`` command that
|
|
can consume the extra metadata in this format.
|
|
|
|
|
|
Availability
|
|
============
|
|
|
|
:program:`ceph-volume-systemd` is part of Ceph, a massively scalable,
|
|
open-source, distributed storage system. Please refer to the documentation at
