Doc Type:	Bug Fix
Doc Text:	Previously, the OpenStack Dashboard LBaaS pool details page would not correctly handle the unexpected case of the subnet attached to an LBaaS pool being deleted. Consequently, if you created a network, subnet, router, and load balancer, and then deleted the network, subnet, and router, but retained the load balancer, the OpenStack Dashboard LBaaS details page would return error 500. This update addresses this issue by checking for this scenario and displaying a warning message instead. As a result, the LBaaS details page now renders correctly and displays a warning as needed.

Description Andrew Spurrier 2014-10-14 09:04:44 EDT

Description of problem:  Deleting a network while a Load Balancer is still defined breaks the Load Balance GUI page.


Version-Release number of selected component (if applicable):
RHELOSP 5

How reproducible:  I imagine completely but I can't test it at this stage because I can not define any more Load Balancers!


Steps to Reproduce:
1.  Via the RHELOSP 5 Web interface
2. Define a network
3. Define a router
4. add an interface to the router
5. add a load balancer
6. delete the interface on the router
7. delete the router
8. delete the network 

Actual results:
The network is deleted and from now on the "Load Balancer" tab on the network page cannot be accessed.
 
> Something went wrong!
> 
> An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator.
> 
> Home
> 
> Help


Expected results:
Error reported that the network cannot be deleted while a "Load Balancer" is defined.

Hi Toni,

Can you please try to reproduce this issue? I am also interested to know what is the behavior in the CLI to determine if this is a Neutron issue or Horizon one.

Thanks,
Nir

Comment 4 lpeer 2015-01-15 04:53:16 EST

Toni - can you please reproduce on OSP-6.

Comment 5 Toni Freger 2015-01-18 02:02:12 EST

Have tested on RHEL7 the latest rhos6  

openstack-neutron-2014.2.1-6.el7ost.noarch
python-django-horizon-2014.2.1-5.el7ost.noarch

The issue has reproduced via Horizon.
In CLI the same behaviour, can delete network even the LB pool exists.

Comment 6 John Schwarz 2015-04-16 10:05:48 EDT

A patch which fixes the GUI error has been merged late January [1] by the community, so it should be fixed in OSP-7.

John.

Comment 7 Toni Freger 2015-06-07 12:32:13 EDT

Alex, please try to reproduce it on the latest puddle.
Pay attention it's LBaaS v1.

Thanks
