** Description changed: - The ceph monitor and osd daemons do not restart automatically on server - reboot on Xenial. + [Impact] + Users of the ceph-osd@ and ceph-mon@ systemd units are not able to reboot servers; the targets which ensure that daemons managed this way are missing from the packages. There is also no nice way to restart all ceph daemons on a machine due to the missing systemd targets. + + [Test Case] + Install ceph-mon and ceph-osd machines + Enable and initialise cluster using ceph-osd@ and ceph-mon@ unit files. + Confirm working + Reboot machines + ceph-mon units will not start automatically after reboot + ceph-osd units will start, but only due to udev rule processing + + [Regression Potential] + Minimal; we're introducing the missing targets to the packages; these targets will be enabled and started on install, and the change to the packaging ensures that the ceph-mon/mds/create-keys systemd service units + provided directly by the packaging are managed as before (not auto enabled and started). + + [Original Bug Report] + The ceph monitor and osd daemons do not restart automatically on server reboot on Xenial. $ apt-cache policy ceph ceph: - Installed: 10.2.2-0ubuntu0.16.04.2 - Candidate: 10.2.2-0ubuntu0.16.04.2 - Version table: - *** 10.2.2-0ubuntu0.16.04.2 500 - 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages - 100 /var/lib/dpkg/status - 10.1.2-0ubuntu1 500 - 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages + Installed: 10.2.2-0ubuntu0.16.04.2 + Candidate: 10.2.2-0ubuntu0.16.04.2 + Version table: + *** 10.2.2-0ubuntu0.16.04.2 500 + 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages + 100 /var/lib/dpkg/status + 10.1.2-0ubuntu1 500 + 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages This is likely caused by the same clash between upstream target files and Ubuntu systemd unit files that is noted in [1] but I have opened a separate bug because I believe the severity of not having Ceph restart automatically on server reboot is higher severity than not being able to start/stop all services with one command, which is what is reported in [1]. The source of the Ubuntu package [2] does not have the necessary target files that upstream Ceph added to allow for restart on reboot under this commit [3] which is included in Ceph's github tag 10.2.2. - [1] https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1627640 [2] https://bugs.launchpad.net/ubuntu/+source/ceph/10.2.3-0ubuntu0.16.04.2 [3] https://github.com/ceph/ceph/commit/15c4ad44010c798af7804e287ba71dcc289f806f
