ceph-volume-systemd − systemd ceph-volume helper tool
ceph−volume−systemd systemd instance name
ceph−volume−systemd is a systemd helper tool that receives input from (dynamically created) systemd units so that activation of OSDs can proceed.
It translates the input into a system call to ceph−volume for activation purposes only.
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.
ceph−volume−systemd is part of Ceph, a massively scalable, open−source, distributed storage system. Please refer to the documentation at http://docs.ceph.com/ for more information.
