Public bug reported: Steps to reproduce: Create HA router (Observe that HA ports were created) Attach an interface Delete router
Result: The deletion fails because the router has an interface attached, however all of its HA ports were deleted, leaving the system in an inconsistent state. Any L3 agents that attempt to configure this HA router will fail because it doesn't have HA ports. Expected behavior: Deletion validations should occur before deleting any resources. The deletion should fail and the router should continue to exist properly, with HA ports and all. Reason: As per https://github.com/openstack/neutron/blob/master/neutron/db/l3_hamode_db.py#L411: When deleting a router, the call first reaches the L3 HA DB mixin, which deletes HA-specific resources first, in its own commit. It then calls to the super class, which will eventually try to delete the router object itself. If any deletion validation fails, the router object itself is not deleted, but the HA ports and their VRID allocations were already deleted and the transaction was commited. ** Affects: neutron Importance: Undecided Status: New ** Tags: juno-backport-potential l3-ha -- You received this bug notification because you are a member of Yahoo!
