Created attachment 1291520 [details] neutron configuration file Description of problem: Director deployment fails when passing the following heat parameter: NeutronServicePlugins: "router,qos,trunk,metering,tag" The failure is: "ValueError: Multiple plugins for service TAG were configured". Version-Release number of selected component (if applicable): openstack-neutron-9.3.1-2.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Deploy OSP 10 and pass this to overcloud deployment: NeutronServicePlugins: "router,qos,trunk,metering,tag" Actual results: Overcloud deployment fails with "ValueError: Multiple plugins for service TAG were configured" Expected results: Overcloud deployment passed successfully Additional info: Attached neutron.conf
The 'tag' service plugin is a 'default service plugin', as defined here: https://github.com/openstack/neutron/blob/stable/newton/neutron/plugins/common/constants.py#L44 Those plugins are loaded automatically. What's happening is that 'tag' is being defined in neutron.conf:service_plugins, so Neutron is trying to load it twice. If you look at controller0 /var/log/neutron/server.log: "2017-06-24 13:15:47.267 89733 DEBUG neutron.manager [-] Loading service plugins: ['router', 'qos', 'trunk', 'metering', 'tag', 'flavors', 'auto_allocate', 'timestamp', 'network_ip_availability', 'tag', 'revisions'] _load_service_plugins /usr/lib/python2.7/site-packages/neutron/manager.py:190" (Note 'tag' appearing twice) Then neutron-server complains that tag was defined twice and errors out. However default tripleo-heat-templates doesn't seem to include tag by default (Good!): https://github.com/openstack/tripleo-heat-templates/blob/2518394c2f45d5514946de962f8dfd13aa7c7377/puppet/services/neutron-base.yaml#L43 I'm assuming something in the CI system is adding the 'tag' service plugin in error. Arie I couldn't find infrared in the RHBZ component list, we can either move this bug to a different component or close it.
Thanks Assaf! Closing this bug.
