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