File 0013-init-add-systemd-service-files.patch of Package ceph
From: Owen Synge <osynge@suse.com> Date: Tue, 2 Sep 2014 15:44:19 +0200 Subject: [PATCH] init: add systemd service files This patch adds systemd service files. It is possible to start and enable multiple instances (per monid, osdid, mds name), e.g. # systemctl start ceph-mon@node01 # systemctl enable ceph-mon@node01 # systemctl start ceph-osd@0 # systemctl enable ceph-osd@0 The ceph cluster can be set in the system config file: /etc/sysconfig/ceph adding or editing the CLUSTER environment variable.
