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.

# According to:

systemd/ceph-mon@.service:Remove ceph-create-keys for mon in systemd ceph-create-keys should not be started on boot of mons with systemd so should not exist as 'After' or 'Wants' for the ceph-mon.service Signed-off-by: Owen Synge <osynge@suse.com>

systemd/ceph-mgr: remove automagic mgr creation hack For kraken we auto-created mgr daemons next to mon daemons with some systemd hackery. This is awkward (you can't not get a new mgr daemon when you deploy a mon), systemd-specific (not implemented for upstart on trusty), and mostly unexpected. Since ceph-mgr daemons are now first-class citizens and required for every cluster, make their deployment explicit and transparent to the administrator. Major upgrades are a rare opportunity to have the administrator's full attention so take advantage of it. This effectively reverts 61d779345e9efbe9a2e3f215af1f1dcf6630f04a and 082199f69dd0bd4c18a5f4baea67a88782586657 (and follow-on fixes).

systemd: use --setuser and --setgroup for all daemons Allow all daemons drop privilege themselves, instead of letting systemd do it. Among other things, this means that admins can conditionally not drop prives by setting setuser match path = /var/lib/ceph/$type/$cluster-$id in their ceph.conf to ease the pain of upgrade.

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>

systemd: Restart Mon after 10s in case of failure In some situations the IP address the Monitor wants to bind to might not be available yet. This might for example be a IPv6 Address which is still performing DAD or waiting for a Router Advertisement to be send by the Router(s). Have systemd wait for 10s before starting the Mon and increase the amount of times it does so to 5. This allows the system to bring up IP Addresses in the mean time while systemd waits with restarting the Mon. Fixes: #18635 Signed-off-by: Wido den Hollander <wido@42on.com>
