"source_type" error while creating LB none

Description Punit Kundal 2017-07-18 13:00:22 UTC 
Created attachment 1300471 [details]
"source_type" error while creating LB

Description of problem:

When trying to create load balancers through the V2 panel which is provided by the openstack-neutron-lbaas-ui package, the create operation fails with the source_type error. 

All works fine through the CLI. When trying to do so via the UI, it fails.


Version-Release number of selected component (if applicable):

# rpm -qa | grep openstack-neutron-lbaas-ui
openstack-neutron-lbaas-ui-1.0.0-1.el7ost.noarch


How reproducible:
Always

Steps to Reproduce:
1. Deploy RHOSP 10 overcloud using director

2. Configure LBaaS using this documentation https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/networking_guide/sec-lbaas

3. Install the openstack-neutron-lbaas-ui package either via direct rpm install or via yum 

4. Restart the httpd service on the controller nodes and try to create LB using V2 panel.

This is what the logs show:

+++
2017-07-17 18:40:49,888 403037 WARNING horizon.exceptions Recoverable error: 'source_type'

2017-07-18 14:50:58,862 601131 WARNING horizon.exceptions Recoverable error: 'source_type'
+++

I could not find any other leads in the logs as to what might be causing this.


Actual results:

Load Balancers are not getting created through the UI

Expected results:

Load Balancers should be created successfully with the UI as the services are up and running on the controller nodes

Additional info:

P.S I don't have enable_lb set to true in my env. it's been set to false.

Hello,
Can we backport this fix to osp12. I see the target release is osp13. Also the workaround in commnet #3 does not work for osp12 we have tested by making the changes within the container and restarting the horizon container. Still doesn't work. Is there any other solution?
Comment 5 Radomir Dopieralski 2018-05-17 07:59:33 UTC 
That is a question to the Neutron team, since the bug was apparently in the plugin.

Martin, can I assign the bug to you, or do you have a better idea how to handle it?

I am not sure what the issue here is with OSP12. I am not from the neutron team,
so probably not the correct one to assign it if it is neutron related.

@Jeremy, I have just run a quick test on an OSP12 lab env and I am able to create a router when configured lbaasv2 and using the above steps from comment 3. What issue you see?


1) configure lbaasv2 
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html/networking_guide/sec-lbaas

2) install the openstack-neutron-lbaas-ui package
# yum install openstack-neutron-lbaas-ui

# rpm -qa |grep openstack-neutron-lbaas-ui
openstack-neutron-lbaas-ui-3.0.1-3.el7ost.noarch

3) enable the lb plugin in OPENSTACK_NEUTRON_NETWORK in the horizon container ( /var/lib/config-data/puppet-generated/horizon/etc/openstack-dashboard/local_settings )
    'enable_lb': True,

4) restart horizon container

I was able to create a route , set the gateway network and add ports via horizon:

Note: I have not done any further functional tests with the created router.
