Description Alex Katz 2020-03-19 10:47:40 UTC

Description of problem:
Openstackclient returns no error in case it failed to remove subnet/port from router.
Remove_interface_from_router method [1] returns the error message back [2] but no action is taken there.


Steps to Reproduce:

openstack network create net_1
openstack router create the_only_router
openstack subnet create --subnet-range 10.100.0.0/24 --network net_1 subnet_1
openstack router add subnet the_only_router subnet_1
openstack router set --external-gateway nova the_only_router
openstack port create --network net_1 port_1
openstack floating ip create --floating-ip-address 10.0.0.201 --port port_1 nova
openstack router remove subnet the_only_router subnet_1


Actual results:
No error message


Expected results:
Router interface for subnet <subnet_id> on router <router_id> cannot be deleted, as it is required by one or more floating IPs.

Comment 4 Bernard Cafarelli 2020-07-17 13:48:20 UTC

I now remember why it looked really familiar, this is the 16 version of bug 1570786 (for 13). I think 14 did not get that backport, but here is the result on 16.1 beta, and on upstream master:
(overcloud) [stack@undercloud-0 ~]$ openstack router remove subnet the_only_router subnet_1
ConflictException: 409: Client Error for url: http://10.0.0.131:9696/v2.0/routers/0d099810-dfee-45b8-90ff-f96dbf077b77/remove_router_interface, Router interface for subnet 70eb8b61-0221-48b6-99d5-64986349dbbd on router 0d099810-dfee-45b8-90ff-f96dbf077b77 cannot be deleted, as it is required by one or more floating IPs.

I will update with matching 16 package and close storyboard
