commit 75f34fbbd930a143ed2c4b868f33c117e467e98e Author: Ed Bak <[email protected]> Date: Mon Sep 29 14:15:52 2014 -0600 Don't fail when trying to unbind a router If a router is already unbound from an l3 agent, don't fail. Log the condition and go on. This is harmless since it can happen due to a delete race condition between multiple neutron-server processes. One delete request can determine that it needs to unbind the router. A second process may also determine that it needs to unbind the router. The exception thrown will result in a port delete failure and cause nova to mark a deleted instance as ERROR.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1367892 Title: delete port fails with RouterNotHostedByL3Agent exception Status in OpenStack Neutron (virtual network service): Fix Released Bug description: When deleting a vm, port_delete sometimes fails with a RouterNotHostedByL3Agent exception. This error is created by a script which boots a vm, associates a floating ip, tests that the vm is pingable, disassociates the fip and then deletes the vm. The following stack trace has been seen multiple times. 2014-09-09 11:55:59 7648 DEBUG neutronclient.v2_0.client [req-16883a09-7ec6-4159-9580-9cfa1880f786 73ae929bd62c4eddbe2f38a709265f2b 3d4668d03b5e4ac7b316aac9ff88e2db] Error message: {"NeutronError": {"message": "The router 0ffc5634-d7ff-4bc7-8dca-cbdb10414924 is not hosted by L3 agent 35f71627-3c41-4226-96dd-15faa6ec44c3.", "type": "RouterNotHostedByL3Agent", "detail": ""}} _handle_fault_response /opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py:1202 2014-09-09 11:55:59 7648 ERROR nova.network.neutronv2.api [req-16883a09-7ec6-4159-9580-9cfa1880f786 73ae929bd62c4eddbe2f38a709265f2b 3d4668d03b5e4ac7b316aac9ff88e2db] Failed to delete neutron port 41b8e31b-f459-4159-9311-d8701885f43a 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api Traceback (most recent call last): 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/nova/network/neutronv2/api.py", line 448, in deallocate_for_instance 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api neutron.delete_port(port) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 101, in with_params 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api ret = self.function(instance, *args, **kwargs) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 328, in delete_port 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api return self.delete(self.port_path % (port)) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 1311, in delete 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api headers=headers, params=params) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 1300, in retry_request 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api headers=headers, params=params) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 1243, in do_request 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api self._handle_fault_response(status_code, replybody) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 1211, in _handle_fault_response 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api exception_handler_v20(status_code, des_error_body) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api File "/opt/stack/venvs/nova/local/lib/python2.7/site-packages/neutronclient/v2_0/client.py", line 68, in exception_handler_v20 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api status_code=status_code) 2014-09-09 11:55:59.153 7648 TRACE nova.network.neutronv2.api Conflict: The router 0ffc5634-d7ff-4bc7-8dca-cbdb10414924 is not hosted by L3 agent 35f71627-3c41-4226-96dd-15faa6ec44c3.
