Our order of operations went as such: - All packages get updated to latest available Ussuri (16.3.1) for Bionic via apt-get dist-upgrade - Stop services (systemctl stop neutron-dhcp-agent; systemctl stop neutron-metadata-agent; systemctl stop neutron-ovs-cleanup; systemctl stop neutron-l3-agent; systemctl stop neutron-openvswitch-agent; systemctl stop neutron-server) - Upgrade database (neutron-db-manage current; neutron-db-manage upgrade heads) - Start services back up (systemctl start neutron-dhcp-agent; systemctl start neutron-metadata-agent; systemctl start neutron-ovs-cleanup; systemctl start neutron-l3-agent; systemctl start neutron-openvswitch-agent; systemctl start neutron-server) - All L3 agents for all routers elect to be down - Rebooted control plane several times while troubleshooting, L3 agents stay down - Found that 16.3.2 was available on staging repository, installed it, all L3 agents go to standby - Install 16.0.0 for Focal (all I could find during my scramble to fix the outage), L3 agents start to elect a master for each router - Later that week, re-attempt 16.3.1, all L3 agents go to standby - Find 16.2.0 for Bionic and downgrade to it, all L3 agents begin to elect masters
