simple
Implements the functionality needed to manage OSDs from the simple
subcommand:
ceph-volume simple
Command Line Subcommands
By taking over management, it disables all ceph-disk
systemd units used
to trigger devices at startup, relying on basic (customizable) JSON
configuration and systemd for starting up OSDs.
This process involves two steps:
The scanning will infer everything that ceph-volume
needs to start the OSD,
so that when activation is needed, the OSD can start normally without getting
interference from ceph-disk
.
As part of the activation process the systemd units for ceph-disk
in charge
of reacting to udev
events, are linked to /dev/null
so that they are
fully inactive.
