Public bug reported: [1] allow us to identify the stale snat namespace and delete the namespace when the gateway is cleared as the agent restarts.
But method SnatNamespace.delete unplugs 'sg-XXX' devices only, leads to stale port remains in ovs bridge. [1] https://review.openstack.org/#/c/326729/ How to reproduce: - create a distributed router, set its router gateway, bind a subnet to it - stop the l3 agent hosting the router - clear the router’s gateway - start the stopped l3 agent, device "sg-XXXX" and snat namespace will be cleaned, stale device “qg-XXXX” will remain. $ sudo ovs-vsctl list port qg-749cbaab-13 _uuid : 7f116611-4885-4813-a938-a9aebf2723ac bond_downdelay : 0 bond_fake_iface : false bond_mode : [] bond_updelay : 0 external_ids : {} fake_bridge : false interfaces : [81e93ffd-ce76-4c75-8522-5ff5e9a4c1c0] lacp : [] mac : [] name : "qg-749cbaab-13" other_config : {net_uuid="eaad0784-47dd-4263-82e1-419e7f3d8e3f", network_type=vxlan, physical_network=None, segmentation_id="101", tag="7"} qos : [] statistics : {} status : {} tag : 4095 trunks : [] vlan_mode : [] ** Affects: neutron Importance: Undecided Assignee: Quan Tian (tianquan23) Status: In Progress -- You received this bug notification because you are a member of Yahoo!
