ceph-volume-systemd – systemd ceph-volume helper tool

Synopsis

ceph-volume-systemdsystemd instance name

Description

ceph-volume-systemd is a systemd helper tool that receives inputfrom (dynamically created) systemd units so that activation of OSDs canproceed.

It translates the input into a system call to ceph-volume for activationpurposes only.

Examples

Its input is the systemd instance name (represented by %i in a systemdunit), and it should be in the following format:

  1. <ceph-volume subcommand>-<extra metadata>

In the case of lvm a call could look like:

  1. /usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41

Which in turn will call ceph-volume in the following way:

  1. ceph-volume lvm trigger  0-8715BEB4-15C5-49DE-BA6F-401086EC7B41

Any other subcommand will need to have implemented a trigger command thatcan consume the extra metadata in this format.

Availability

ceph-volume-systemd is part of Ceph, a massively scalable,open-source, distributed storage system. Please refer to the documentation athttp://docs.ceph.com/ for more information.
