After this, I tried update the quotas with neutron quota-update command as follows:

It appears that quota-update operations are working fine with LBaaS V1.

quota-update operations on LBaaS V2:

+++
[stack@instack ~]$ neutron quota-update --member 10
Unrecognized attribute(s) 'member'

[stack@instack ~]$ neutron quota-update --health-monitor 20
Unrecognized attribute(s) 'health_monitor'

[stack@instack ~]$ neutron quota-update --vip 20   <- actually not needed, just tested it for completeness
Unrecognized attribute(s) 'vip'

surprisingly, the pool quota could be update without any issues:

 [stack@instack ~]$ neutron quota-update --pool 50  <- this is what is even more confusing

From the above results, it can be seen that, quota-update operations are working but only for LBaaS V1 agent and not the V2 agent.


Actual results:

can not update lbaas v2 quotas with neutron quota-update

I can't find any option for setting quota of loadbalancer either

[stack@instack ~]$ neutron help quota-update
usage: neutron quota-update [-h]
                            [-f {html,json,json,shell,table,value,yaml,yaml}]

                            [--health-monitor health_monitors]


Expected results:

quota update operations should work when lbaas v2 agent is running

Hi,

We are very close to resolving this.
My investigation shows that we'll need to cherry-pick

client:
https://review.openstack.org/#/c/356862/
https://review.openstack.org/#/c/371297/

neutron-lbaas bugs:
https://review.openstack.org/#/c/373135/
https://review.openstack.org/#/c/368217/

Internal tests show that when all 4 patches are included, quota updates work as expected:

---------------------+-------+
| Field               | Value |
+---------------------+-------+
| floatingip          | 50    |
| healthmonitor       | 1234  |
| listener            | 1234  |
| loadbalancer        | 1234  |
| member              | 1234  |
| network             | 10    |
| pool                | 1234  |
| port                | 50    |
| rbac_policy         | 10    |
| router              | 10    |

+---------------------+-------+

Comment 9 Nir Magnezi 2017-08-24 09:18:35 UTC
Please note that this fix consists of both neutronclient and neutron-lbaas patches. Thus, one should update both packages:

1. Client: python-neutronclient-3.1.0-4.el7ost
2. neutron-lbaas: as specified in bug 1482671
