commit 98de72e9f32090a93c9c1b6f45cc0f2385c27792 Author: Kevin Benton <[email protected]> Date: Sat Sep 24 01:53:38 2016 -0700 Don't try to delete non-existent namespace The namespace in the DHCP agent may already have been deleted by a previous event when _destroy_namespace_and_port is called (e.g. all subnets deleted from network and then network is deleted). To avoid log errors every time this happens, check for the existence of the namespace before trying to delete it. Closes-Bug: #1627691 Change-Id: I204ba7a0de056f13af505541d67f0acdd70fd54d ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1627691 Title: non-existent namespace errors in DHCP agent Status in neutron: Fix Released Bug description: The DHCP agent log gets sprinkled with ERROR logs when a call to disable DHCP for a network happens twice. This can happen if an agent's port is deleted and then a delete network call for its network happens before it resyncs (both events call 'disable' on the driver). http://logs.openstack.org/91/375791/9/check/gate-tempest-dsvm-neutron-dvr-ubuntu-xenial/16e9b8f/logs/screen-q-dhcp.txt.gz?level=TRACE 2016-09-25 12:56:37.463 15334 ERROR neutron.agent.linux.utils [req- 3882fc97-98a1-410e-8638-4de87841e5ee - -] Exit code: 1; Stdin: ; Stdout: ; Stderr: Cannot remove namespace file "/var/run/netns/qdhcp- 3e0f2433-c53d-43e4-8c1e-5c6b863ad693": No such file or directory 2016-09-25 12:56:37.463 15334 WARNING neutron.agent.linux.dhcp [req-3882fc97-98a1-410e-8638-4de87841e5ee - -] Failed trying to delete namespace: qdhcp-3e0f2433-c53d-43e4-8c1e-5c6b863ad693 2016-09-25 12:57:24.774 15334 ERROR neutron.agent.linux.utils [req-113e268a-f42d-4a45-8e4e-e5530a14f43f - -] Exit code: 1; Stdin: ; Stdout: ; Stderr: Cannot remove namespace file "/var/run/netns/qdhcp-82696d3a-3ef9-4744-a685-cfd38730b541": No such file or directory 2016-09-25 12:57:24.774 15334 WARNING neutron.agent.linux.dhcp [req-113e268a-f42d-4a45-8e4e-e5530a14f43f - -] Failed trying to delete namespace: qdhcp-82696d3a-3ef9-4744-a685-cfd38730b541 2016-09-25 12:57:32.672 15334 ERROR neutron.agent.linux.utils [req-702f653b-f69b-485b-917f-9231622a5fae - -] Exit code: 1; Stdin: ; Stdout: ; Stderr: Cannot remove namespace file "/var/run/netns/qdhcp-4a536dcd-5047-4c39-91cb-30ab11cb3d73": No such file or directory 2016-09-25 12:57:32.673 15334 WARNING neutron.agent.linux.dhcp [req- 702f653b-f69b-485b-917f-9231622a5fae - -] Failed trying to delete namespace: qdhcp-4a536dcd-5047-4c39-91cb-30ab11cb3d73 To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1627691/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
