@axino yes switching between ha/non-ha is support so long as the router is in admin state false at the time of change (which I believe is the case in this issue).
Some further observations; switching a router from ha mode to non-ha mode should remove all existing router agent hosting arrangements and then re-schedule the new non-ha router on an appropriate agent. In the cloud experiencing this issue, I see only one remaining qrouter namespace but its also still got a keepalived and state monitor running - which I don't think is right. I'm wondering whether due to the sheer number of routers being hosted on each network node, the router never gets removed before being rescheduled back to the same node, resulting in the teardown being skipped in someway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749425 Title: Neutron integrated with OpenVSwitch drops packets and fails to plug/unplug interfaces from OVS on router interfaces at scale To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1749425/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
