Process management
In IBM Storage Ceph, all process management is done
through the systemd service. Each time you want to start, restart,
and stop the Ceph daemons, you must specify the daemon type or the daemon
instance.
For more information on using systemd, see the Introduction to systemd and Managing system services with systemctl chapters within the Configuring basic system settings guide within the Product Documentation for Red Hat Enterprise Linux for your OS version, on the Managing system services with systemctl.
