zhouhanHi17:15
*** Franky_T has joined #openvswitch17:15
mmichelsonHi everyone. I'll go first real quick17:16
mmichelsonI've got a small improvement to be able to gather pinctrl stats. You can find my WIP here: https://github.com/putnopvut/ovn/tree/pinctrl_stats17:17
mmichelsonRight now it just keeps track of the count of packet-in operations that occur per port binding.17:17
mmichelsonI emailed Jeremy Kerr again earlier this week about getting a separate OVN project for patchwork, but I never heard back from him. So I'll need to ping him again to see what needs to be done on our end to facilitate it.17:18
mmichelsonOther than that, it's mostly been helping to put out fires for Red Hat customer issues.17:19
mmichelsonAnd that's it for me.17:19
mmichelsonhm, quiet day.17:21
zhouhanI can go next17:22
zhouhanI continued working on ovn scale test, comparing between versions. The basic findings so far is that 20.03/06's northd spent much more time than 2.12. Second finding is 20.06's ovn-controller I-P has reduced number of lflow_runs.17:24
zhouhanI still didn't got time to dig out the reason why 20.03 started to spent almost doubled time in northd. That will be my next target.17:24
numanszhouhan, no regressions in ovn-controller due to the I-P patches right ?17:26
zhouhanFor the e2e latency, it seems the I-P improvement recently done in 20.06 doesn't help much. I.e. 20.03 and 20.06 shows similar result. I think it is due to the flow comparing part. I will work on incrementally install the flows without full comparison, and see how it improves.17:27
zhouhannumans: No regression seen on my testing :)17:27
numansok. good to hear about that17:27
numansgiven that there were quite a few regressions earlier17:28
zhouhanapart from this, there were lots of questions and discussions in the ML, I tried my best to answer some of them. I think it is a good sign that OVN is getting more and more popular :)17:28
zhouhanHowever, it seems some documentation needs to be further improved, especially for the OVN DB clustering.17:29
numansagree.17:29
zhouhanOh, finally, thanks dceara for fixing the RAFT bug I introduced, which caused the inconsistancy problem.17:30
zhouhanthat's it from me17:30
dcearazhouhan: no problem, it's good that we figured it out.17:30
numansI can go real quick next.17:30
numansNot much on the OVN patches this week.17:30
numansI was busy with mmichelson on some issues.17:31
numansnot much reviews this week. But I'll review zhouhan's ARP patches after this meeting.17:31
zhouhanthanks numans17:31
numansAnd request review these patches - https://patchwork.ozlabs.org/project/openvswitch/list/?series=19400417:32
numansThat's it from me.17:32
dcearanumans: I'm looking at them as we speak :)17:32
zhouhanI forgot to mention that it would be appreciated if someone could help review this: #link https://patchwork.ozlabs.org/project/openvswitch/patch/1596217711-11945-1-git-send-email-hzhou@ovn.org/17:33
dcearazhouhan: ack, i'll put it on my list for tomorrow17:33
zhouhandceara: thanks!17:33
numansdceara, thanks.17:34
dcearaI have a quick update too: except for the RAFT issue I found a bug in the IGMP code that was uncovered when ovn-k8s moved to ovn-monitor-all. #link https://patchwork.ozlabs.org/project/openvswitch/list/?series=19444917:36
dcearaAnd I was planning to do a round of reviews today/tomorrow. That's it on my side, thanks!17:37
numansOne last point from me, I need some attention on this patch too https://patchwork.ozlabs.org/project/openvswitch/patch/20200709091156.773306-1-numans@ovn.org/. Ankur and I are having discussions there. It would be nice to get comments from others too.17:37
numansdceara, I'll take a look.17:37
dcearanumans: thanks!17:37
mmichelsonAnybody else?17:38
imaximetsNo much updates from me.  I'm just looking at DB inconsistency fix from dceara.  Will likely apply it today or tomorrow.17:39
dcearaimaximets: thanks!17:39
dcearaimaximets: I assume it's ok to backport it to 2.13, right?17:40
imaximetsdceara, it should go down to 2.12, I think.17:40
dcearaimaximets: great, thanks17:40
imaximetsdceara, np.  thanks for fixing!17:41
mmichelsonAll right everyone thanks for the updates. Talk to you next week17:42
numansBye17:42

dcearazhouhan: one thing I forgot during the meeting, I also sent a PR to ovn-scale-test with all the downstream changes we were using for our testing.17:44
dcearazhouhan: It would be great if you could have a look at some point. It's not really urgent but we'd like to move to using ovn-scale-test master in the future.17:44
zhouhandceara: ok, I will take a look. (I have some changes, too, to be posted)17:45
dcearazhouhan: ack, thanks17:45
