commit f787f12aa3441ecffef55f261c4d87dbb12ca6cf Author: Slawek Kaplonski <[email protected]> Date: Fri Sep 28 13:07:28 2018 +0200 Make port binding attempt after agent is revived In some cases it may happen that port is "binding_failed" because L2 agent running on destination host was down but this is "temporary" issue. It is like that for example in case when using L3 HA and when master and backup network nodes were e.g. rebooted. L3 agent might start running before L2 agent on host in such case and if it's new master node, router ports will have "binding_failed" state. When agent sends heartbeat and is getting back to live, ML2 plugin will try to bind all ports with "binding_failed" from this host.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1794809 Title: Gateway ports are down after reboot of control plane nodes Status in neutron: Fix Released Bug description: Sometimes when control plane nodes are going down and then up it may happen that for L3 HA routers, failover of active router will happen and in such case if L3 agent will be running before openvswitch agent on host, gateway port may be in "binding failed" state on new MASTER agent. That will cause no connectivity to floating IPs on this router. I tested this on Queens but it seems that there wasn't any changes in this since Queens. One possible solution might be to trigger another bind attempt for all ports which are binding_failed on host when L2 agent from this host is revived. I will investigate if that would work.
