Description Jon Jozwiak 2016-08-19 21:24:42 UTC
Description of problem:
In Horizon in RHEL OSP 9 (Mitaka) when I click on 'Edit Load Balancer' within the Load Balancers v2 tab, I get an error message as follows: 

Danger: An error occurred.  Please try again later.  

Version-Release number of selected component (if applicable):
RHEL OSP 9 (Mitaka)


How reproducible:
This occurs consistently 

Steps to Reproduce:
1. Use the CLI to create a load balancer with pool, members, listener, etc
2. Validate load balancer is balancing traffic between 2 VMs
3. Log into Horizon Dashboard
4. Click on project tab in upper left hand corner
5. Click Network -> Load Balancers V2 
6. Click the 'Edit Load Balancer' button for your load balancer

Actual results:
An error box pops up:
Danger: An error occurred.  Please try again later. 

Expected results:
I'd expect it to let me edit the load balancer

Additional info:

Below is the output in /var/log/horizon/horizon.log

Comment 3 Nir Magnezi 2016-09-14 13:52:18 UTC

Can you please share some details about your setup? (So I can debug the issue).
How was it deployed, rpm versions, how was LBaaS configured (by the installer? manually?), etc.

Please also attach relevant logs and configuration files.

Comment 4 Jon Jozwiak 2016-09-26 16:01:19 UTC
I built the environment with a packstack all in one build.  Then I added LBaaS v2 as follows: 

yum -y install openstack-neutron-lbaas haproxy

# In /etc/neutron/neutron.conf, add lbaasv2 to service plugins.
service_plugins = neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2

# In [service_providers] section of /etc/neutron/neutron.conf, add the load balancer with haproxy backend:

# Set the interface driver to openvswitch (or linuxbridge if applicable)
openstack-config --set /etc/neutron/lbaas_agent.ini DEFAULT interface_driver openvswitch

# Ensure the device_driver is commented out if it was previously defined for v1
sed -i -e 's/^device_driver/#device_driver/g' /etc/neutron/

# Run the database migration
neutron-db-manage --subproject neutron-lbaas upgrade head
systemctl disable neutron-lbaas-agent
systemctl stop neutron-lbaas-agent
systemctl restart neutron-server
systemctl enable neutron-lbaasv2-agent
systemctl start neutron-lbaasv2-agent

# Enable the v2 UI 
yum -y install openstack-neutron-lbaas-ui

# Ensure the following section in /etc/openstack-dashboard/local_settings:
    'enable_lb': True,

systemctl restart httpd

Comment 6 Assaf Muller 2018-11-21 17:07:26 UTC
Closed due to low prioritization. It doesn't make sense to invest in LBaaS v2 UI at this point, as we focus on Octavia on OSP 13+.
