This document is for a development version of Ceph.
After identifying the correct volume it will then proceed to mount it by using the OSD destination conventions, that is:
/var/lib/ceph/osd/<cluster name>-<osd id>
For our example OSD with an id of
0, that means the identified device will
be mounted at:
Once that process is complete, a call will be made to start the OSD:
systemctl start ceph-osd@0
The systemd portion of this process is handled by the
trigger sub-command, which is only in charge of parsing metadata coming from
systemd and startup, and then dispatching to
ceph-volume lvm activate which
would proceed with activation.
