Description rdobosz 2022-04-26 12:02:56 UTC

Description of problem:

Sometimes it happens, that due to Neutron slowness, we may end up with several ports being created inside Kuryr created network, while in a state DOWN and without the tag which indicates service who created it. That means, OpenShift installer cannot successfully remove such Neutron networks because of existing resources (ports in this case).

According to the duplicate bug https://bugzilla.redhat.com/show_bug.cgi?id=2060413 this is at least present in 4.10. How far do we need to backport this fix? Could you set the Version field accordingly?

Comment 8 Itzik Brown 2022-05-11 19:17:19 UTC

Verified with
4.11.0-0.nightly-2022-05-11-054135
RHOS-16.2-RHEL-8-20220311.n.1

Steps:
1. Created deployment in its own namespace
   $ oc new-project demo2
   $ oc create deployment  --image quay.io/kuryr/demo demo2
2. Created two ports manually in the newly created neutron network
    $ openstack port create --network demo2 port2-2
    $ openstack port create --network demo2 port2-2
3. Deleted ns 
    $ oc delete ns demo2

Deletion tool less than 30 seconds
