NAME

6       ceph-volume-systemd - systemd ceph-volume helper tool
7

SYNOPSIS

9       ceph-volume-systemd systemd instance name
10
11

DESCRIPTION

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

EXAMPLES

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
