Re: [Starlingx-discuss] [OpenStack Ussuri Upgrade Task] Call for patch review!!

1 Jun 2020

      Hi Frank,

I also tested the issue 2 with latest daily build on duplex setup.
The conclusion is that the issue is there all the time. 
This issue might not be fixed soon, but should not block OpenStack upgrade, right? 

For 9 OpenStack patches below, I have removed all workflow-1, except the first patch and add depends-on all them.
https://review.opendev.org/#/q/topic:for_ussuri+(status:open)
Your review and comments are welcome!

As for issue 2, some detail info FYI.
It also needs to wait for around 10 min before all pods are ready again after reboot for master build.
It stuck on below 2 pods for 10 min. The same as the one I saw with my OpenStack upgrade engineering build. 
     neutron-ovs-agent-controller-0-937646f6-xxznw(depends openvswitch-db)
     openvswitch-db-8fxkw

Is it the same stability issue as the one reported from your test team?  I can only see this issue after force rebooting.  What is our expected recovery time?
Your comment is appreciated! 

Thanks!

Hi Frank,

Glad to see your quick reply!!
For OpenStack upgrade task, we have finished all test and get patches ready for more than 2 weeks, but no any review comments and feedback from your side.  What's the next step?

For issue # 2,  in community meeting notes,  I saw that you had some stability issue from WR local test team. But so far, I do not see any LP for the detail info. You should ask them to do that!  Right?

According to your concern, I tried to reproduce it with my build (cherry pick OpenStack upgrade patches)yesterday, and the original issue [1] was not seen any more, mariadb got ready quickly, no regression.

Thanks!

Thanks Zhipeng.

Good to see progress on IPv6.
Waiting for 10 minutes for pods to recover isn't a good result.  Is there a LP open on this issue?  Which pods are not ready? What can you tell us about this 10 minute outage?

Frank

Hi Frank,

Nicolae already added test case description. Thanks Nicolae!

I also did below test on AIO-DX virtual setup, exactly according to your mentioned steps.
No issue found, but just need to wait for around 10 min before all pods are ready again after reboot.

For ipv6 issue, I have submitted new patch for it since dynamic override for database config did not work.

Zhipeng:

Thanks for the info.  You have provided the # of testcases but not what those testcase do.  Where can I find a description of what the OpenStack testcases do?

For the controller reset testcases I'd like to see the test result for the following:
Is openstack usable during the following scenarios on AIO-DX and on Standard configurations:
- Lock/unlock of standby controller
- reset (ie: reboot -f) of the standby controller
- reset (ie: reboot -f) of the active controller
- reapply of stx-openstack after the above scenarios

3) Another 2 test
    a) Using IPv6
         It can pass with workaround now.  I need one more fix for it.
         In my previous patch https://review.opendev.org/#/c/716524 (merged), I dynamically override below 
            config_override: |
                [mysqld]
                bind_address=::
         However, it did not work now. From log,  it shows error "OpenStack-Helm Mariadb - INFO - b'error: Found option without preceding group in config file: /etc/mysql/conf.d/20-override.cnf at line: 1'"
         I tried many methods, but could not remove the first line in 20-override.cnf
                mysql@mariadb-server-0:/etc/mysql/conf.d$ cat 20-override.cnf
                |-     
                [mysqld]
                bind_address=::
        I can only add it in manifest.yaml as a static override like below.
               values:
                  conf:
                      database:
                          config_override: |
                              [mysqld]
                              bind_address=::

    b) Reset of controllers and check status of OpenStack while a controller is rebooting.
         I have tested it and pass on simplex.
         For duplex, I have a setup issue in my side.
         @Jascanu, Nicolae  Could you help me on it for duplex test, if you have time today. Thanks!

Zhipeng:

Can you publish the list of tests that have been run for openstack?

Also has openstack been tested for the following scenarios:
1) Using IPv6
2) Reset of controllers and check status of openstack while a controller is rebooting?

I would strengthen that to no changes until we get Green Sanity other than what's required to make them Green.

Full Stop!

Sau!

Hi all,
Please help to review OpenStack Ussuri upgrade patches.
Our target is to get all below patches merged by end of next week.
https://review.opendev.org/#/q/topic:for_ussuri+(status:open+OR+status
:merged)
During OpenStack upgrade for StarlingX, we have to move python2.7 to
python3.6 for OpenStack services as ussuri release only support python3.
We also rebased openstack-helm/helm-infra to latest version.
Engineering build test status.
1. nfv_scenario_tests PASS on simplex/duplex/multi virtual setup.
 2. nfv_scenario_tests PASS on simplex bare metal setup.
 3. Sanity test is ongoing.   Duplex/standard virtual setup test PASS.
Thanks!
