Public bug reported: In Fullstack tests: neutron.tests.fullstack.test_ports_rebind.TestVMPortRebind.test_vm_port_rebound_when_L2_agent_revived and neutron.tests.fullstack.test_ports_rebind.TestRouterPortRebind.test_vm_port_rebound_when_L2_agent_revived L2 agent is disabled, test is waiting for agent to be DOWN and then it tries to create port which is marked as "binding failed" due to dead agent on the compute node.
In some cases like: http://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_abf/901827/1/check/neutron-fullstack-with-uwsgi/abf43a8/testr_results.html or http://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_607/901894/6/check/neutron-fullstack-with-uwsgi/6071fab/testr_results.html it may happen that L2 agent is found dead already but immediately after it is reported like that to the client, it is revived because heartbeat was just received. In the meantime test's client is creating port expecting that this port will be failed to bound but it's actually bound properly and test fails. ** Affects: neutron Importance: High Assignee: Slawek Kaplonski (slaweq) Status: Confirmed ** Tags: fullstack gate-failure -- You received this bug notification because you are a member of Yahoo!
