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.

Description=Ceph object storage daemon osd.%i
systemd: Start OSDs after MONs Currently, we start/stop OSDs and MONs simultaneously. This may cause problems especially when we are shutting down the system. Once the mon goes down it causes a re-election and the MONs can miss the message from the OSD that is going down.

logrotate.conf: fixes for systemd Before this patch, the command 'logrotate -f /etc/logrotate.d/ceph' was generating an error "Failed to reload ceph.target: Job type reload is not applicable for unit ceph.target". Before we issue systemctl reload, check that there is at least one active ceph-* service. (The hyphen is significant.)

systemd: Add systemd sandboxing to services. This change makes it so the mon/osd/mds/radosgw daemons: o Cannot write to /usr, /etc, and /boot. o Cannot access /home, /root, or /run/user. o Each daemon gets its own private /tmp and /var/tmp. o All daemons get a private /dev without physical devices (exception: osd) I'm not sure if the osd daemon needs access to a full /dev so I left ProtectDevices out for ceph-osd@.service.

Drop any systemd imposed process/thread limits If systemd has task accounting enabled, a default of 512 tasks will be applied to all systemd units. For ceph, this is way to low even for a modest cluster, so stop this restriction being applied and allow administrators to apply limits using sysctl. Signed-off-by: James Page <james.page@ubuntu.com>

systemd: Use the same restart limits as upstart Currently, the systemd daemons are not restarted on failure. This patch adds this functionality and sets the defaults to those defined in upstart. This resolves to 3 fails per 30 minutes for osd, mon and mds and 5 fails per 30 seconds for radosgw. Signed-off-by: Boris Ranto <branto@redhat.com>

build/ops: restart ceph-osd@.service after 20s instead of 100ms Instead of the default 100ms pause before trying to restart an OSD, wait 20 seconds instead and retry 30 times instead of 3. There is no scenario in which restarting an OSD almost immediately after it failed would get a better result. It is possible that a failure to start is due to a race with another systemd unit at boot time. For instance if ceph-disk@.service is delayed, it may start after the OSD that needs it. A long pause may give the racing service enough time to complete and the next attempt to start the OSD may succeed. This is not a sound alternative to resolve a race, it only makes the OSD boot process less sensitive. In the example above, the proper fix is to enable --runtime ceph-osd@.service so that it cannot race at boot time. The wait delay should not be minutes to preserve the current runtime behavior. For instance, if an OSD is killed or fails and restarts after 10 minutes, it will be marked down by the ceph cluster. This is not a change that could break things but it is significant and should be avoided. Refs: http://tracker.ceph.com/issues/17889 Signed-off-by: Loic Dachary <loic@dachary.org>
