Public bug reported: http://logs.openstack.org/80/200380/3/gate/gate-tempest-dsvm-neutron- full/2b49b0d/logs/screen-q-dhcp.txt.gz?level=TRACE#_2015-07-22_09_30_43_303
This kind of stuff is really annoying in debugging failures in the gate since I think it's a known failure during cleanup of ports when deleting an instance, so we shouldn't stacktrace this and log as an error, just handle it in the code and move on. 2015-07-22 09:30:43.303 ERROR neutron.agent.dhcp.agent [req-c7faddea-956c-4544-8ec0-1f6e5029cae1 tempest-NetworksTestDHCPv6-1951433064 tempest-NetworksTestDHCPv6-996832218] Unable to reload_allocations dhcp for 301ef35d-2482-4a13-a088-f456958e878a. 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Traceback (most recent call last): 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/dhcp/agent.py", line 115, in call_driver 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent getattr(driver, action)(**action_kwargs) 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/linux/dhcp.py", line 432, in reload_allocations 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent self._release_unused_leases() 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/linux/dhcp.py", line 671, in _release_unused_leases 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent self._release_lease(mac, ip, client_id) 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/linux/dhcp.py", line 415, in _release_lease 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent ip_wrapper.netns.execute(cmd, run_as_root=True) 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/linux/ip_lib.py", line 701, in execute 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent extra_ok_codes=extra_ok_codes, **kwargs) 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent File "/opt/stack/new/neutron/neutron/agent/linux/utils.py", line 138, in execute 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent raise RuntimeError(m) 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent RuntimeError: 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Command: ['ip', 'netns', 'exec', u'qdhcp-301ef35d-2482-4a13-a088-f456958e878a', 'dhcp_release', 'tapcb2fa9dc-f6', '2003::e6ef:eb57:47b4:91cf', 'fa:16:3e:18:e6:78'] 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Exit code: 1 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Stdin: 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Stdout: 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent Stderr: cannot setup interface: No such device 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent 2015-07-22 09:30:43.303 8230 ERROR neutron.agent.dhcp.agent http://logstash.openstack.org/#eyJzZWFyY2giOiJtZXNzYWdlOlwiU3RkZXJyOiBjYW5ub3Qgc2V0dXAgaW50ZXJmYWNlOiBObyBzdWNoIGRldmljZVwiIEFORCB0YWdzOlwic2NyZWVuLXEtZGhjcC50eHRcIiIsImZpZWxkcyI6W10sIm9mZnNldCI6MCwidGltZWZyYW1lIjoiNjA0ODAwIiwiZ3JhcGhtb2RlIjoiY291bnQiLCJ0aW1lIjp7InVzZXJfaW50ZXJ2YWwiOjB9LCJzdGFtcCI6MTQzNzU3NjE3ODQzNn0= ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
