Examples (3) from the manual page, untested
<ceph-volume subcommand>-<extra metadata>
Its input is the systemd instance name (represented by %i in a systemd unit), and it should be in the following format:/usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
In the case of lvm a call could look like:ceph-volume lvm trigger 0-8715BEB4-15C5-49DE-BA6F-401086EC7B41
Which in turn will call ceph-volume in the following way:
