OpenStack Networking (Neutron)
f2e3ab3805
This patch implements the proposed solution from LP #2024205 where upon a Neutron being killed, it could trigger the deletion of the entries from the ovn_hash_ring table that matches the server hostname. When this happens on all controllers this could lead to the ovn_hash_ring being rendered empty which will result in ML2/OVN not processing any OVSDB events. Instead of removing the nodes from the ovn_hash_ring table at exit, this patch changes the code to just mark them as offline instead. That way, the nodes will remain registered in the table and the heartbeat thread will set them as online again on the next beat. If the service is stopped properly there won't be any heartbeat anymore and the nodes will be seeing as offline by the Hash Ring Manager (same as if they were deleted). For more info see LP #2024205.
