13 ceph-volume-systemd is a systemd helper tool that receives input from
14 (dynamically created) systemd units so that activation of OSDs can pro‐
15 ceed.
16
17 It translates the input into a system call to ceph-volume for activa‐
18 tion purposes only.
19
21 Its input is the systemd instance name (represented by %i in a systemd
22 unit), and it should be in the following format:
23
24 <ceph-volume subcommand>-<extra metadata>
25
26 In the case of lvm a call could look like:
27
28 /usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
29
30 Which in turn will call ceph-volume in the following way:
31
32 ceph-volume lvm trigger 0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
33
34 Any other subcommand will need to have implemented a trigger command
35 that can consume the extra metadata in this format.
36
38 ceph-volume-systemd is part of Ceph, a massively scalable, open-source,
39 distributed storage system. Please refer to the documentation at
40 http://docs.ceph.com/ for more information.
