Public bug reported: I have three controller nodes and the Neutron servers on these controllers are set behind Pacemaker and HAProxy to realize active/active HA using DevStack. MariaDB Galera cluster is used as my database backend.I am using the latest codes.
If one port is added as multiple routers' interfaces, the expected result is that only API request is executed successfully and the port is associated to one router. Other API requests would recieve error message like PortInUseClient: Unable to complete operation on port d2c97788-61d7-489a-8b20-7a6e8e39a217 for network 496de8cf-4284-41d7-ad6b-7dd5f232dc21. Port already has an attached device 1b316d80-f5d8-4477-88df-54b376c4c8cd. Besides, in routerports database, only one record of port is allowed to exist. However, if we run two commands to add one port as two different routers' interfaces at the same time. Both of the commands would show execution succeed. The truth is two records that the port is associated to both routers are listed in routerports database. How to reproduce Step 1: Create two routers $ neutron router-create router-1 $ neutron router-create router-2 Step 2: Create an internal network $ neutron net-create net1 Step 3: Add a subnet to the network $ neutron subnet-create --name subnet1 net1 192.166.100.0/24 Step 4: Create a port in the network $ neutron port-create --name port1 net1 Step 5: Add this port as two routers' interfaces at the same time On controller1: $ neutron router-interface-add router-1 port=port1 on controller2: $ neutron router-interface-add router-2 port=port1 Both commands would return success, as shown http://paste.openstack.org/show/483840/ Step 6: Check port list on both routers The result is shown http://paste.openstack.org/show/483843/ As we can see, only one router is successfully associated to the port Step 7: Check routerports database http://paste.openstack.org/show/483842/ where '99276755-236a-44b7-bf97-b2234d97028b' is the port_id of the port we created in Step 4. To sum up, we have two issues here a) Only one API request is executed successfully, but both commands return success b) Routerports database is updated twice and we need to delete the older record.
