Public bug reported: In the systemd service we make use of the `ovn-ctl` script `run_nb_ovsdb` and `run_sb_ovsdb` sub-commands introduced in [0]. These sub-commands fit nicely with systemd's expectations of modern daemons to no longer detachand run in the background.
However, the change in [0] has the side effect of disabling automatic upgrading of clustered databases. Previously this would have been done on every startup [1]. A recent commit to master [2] addresses this and uses the combination of presence of `--db-*-cluster-local-addr` and non-presence of the `--db -*-cluster-remote-addr` to determine if the upgrade should be run. We should backport [2] to our supported OVN packages to prepare for supporting upgrades that require database schema changes. We may also need to change the behavior of the ovn-central charm to not set the `--db-*-cluster-remote-addr` argument on the leader unit. 0: https://github.com/ovn-org/ovn/commit/6444059b5f9444ce06634794d275257f945a6ce5 1: https://github.com/ovn-org/ovn/blob/5c2d311b8b7b4d5c3a619de72be6a433aa4c44db/utilities/ovn-ctl#L312-L314 2: https://github.com/ovn-org/ovn/commit/67e2f386cc838d0b0f9b4b5da7fe611e1113b70c ** Affects: charm-ovn-central Importance: Medium Status: Triaged ** Affects: ovn (Ubuntu) Importance: Medium Status: Triaged ** Changed in: ovn (Ubuntu) Status: New => Triaged ** Changed in: ovn (Ubuntu) Importance: Undecided => Medium ** Also affects: charm-ovn-central Importance: Undecided Status: New ** Changed in: charm-ovn-central Status: New => Triaged ** Changed in: charm-ovn-central Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907081 Title: OVN database is not upgraded on package upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/charm-ovn-central/+bug/1907081/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
