NAME

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

SYNOPSIS

ceph-volume-systemd systemd instance name

DESCRIPTION

ceph-volume-systemd is a systemd helper tool that receives input from (dynamically cre‐ ated) 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

ceph-volume-systemd is part of Ceph, a massively scalable, open-source, distributed stor‐ age system. Please refer to the documentation at http://docs.ceph.com/ for more informa‐ tion.
