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 cluster monitor daemon
systemd: Support Graceful Reboot for AIO Node Ceph AIO installation with single/multiple node is not friendly for loopback mount, especially always get deadlock issue during graceful system reboot. We already have `rbdmap.service` with graceful system reboot friendly as below: [Unit] After=network-online.target Before=remote-fs-pre.target Wants=network-online.target remote-fs-pre.target [Service] ExecStart=/usr/bin/rbdmap map ExecReload=/usr/bin/rbdmap map ExecStop=/usr/bin/rbdmap unmap-all This PR introduce: - `ceph-mon.target`: Ensure startup after `network-online.target` and before `remote-fs-pre.target` - `ceph-*.target`: Ensure startup after `ceph-mon.target` and before `remote-fs-pre.target` - `rbdmap.service`: Once all `_netdev` get unmount by `remote-fs.target`, ensure unmap all RBD BEFORE any Ceph components under `ceph.target` get stopped during shutdown The logic is concept proof by <https://github.com/alvistack/ansible-role-ceph_common/tree/develop>; also works as expected with Ceph + Kubernetes deployment by <https://github.com/alvistack/ansible-collection-kubernetes/tree/develop>. No more deadlock happened during graceful system reboot, both AIO single/multiple no de with loopback mount.

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: 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.

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>
