I agree that there is a behavioural difference between the systemd configurations provided by upstream, and the systemd configuration in distro (and the reason why is outlined in bug 1627640).
Services not restarting post reboot is not something I've seen (deploying using charms which don't do anything specific with regards to systemd configurations). Can you confirm which systemd service is used for the ceph-mon's in ceph ansible? I think this is most likely the cause - the vanilla ceph-mon service provided by the Ubuntu and Debian packaging should automatically startup on reboots, but I'm not 100% sure about the ceph-mon@ version provided by upstream packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646583 Title: Ceph mon and osd don't restart on reboot with Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1646583/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
