I've gone through the 2 errors initially reported: 1. Concurrency issues with HA ports: fixed by https://review.openstack.org/#/c/257059/ (introduction of the ALLOCATING status for routers)
2.

Unable to process HA router %s without HA port (HA router initialize) 2. AttributeError: 'NoneType' object has no attribute 'config' (HA router deleting procedure) With the newest neutron code, I find a infinite loop in _safe_router_removed. Consider a HA router without HA port was placed in the l3 agent, usually because of the race condition. Infinite loop steps: 1. a HA router deleting RPC comes 2. l3 agent remove it 3. the RouterInfo will delete its the router namespace(self.router_namespace.delete()) 4. the HaRouter, ha_router.delete(), where the AttributeError: 'NoneType' or some error will be raised. 5. _safe_router_removed return False 6. self._resync_router(update) 7. the router namespace is not existed, RuntimeError raised, go to 5, infinite loop 5 - 7 To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1533441/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
