Description David Eads 2020-09-21 14:29:29 UTC

ovn on gcp passes about 25% of the time, versus about 60% for azure and aws.

https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-informing#release-openshift-ocp-installer-e2e-gcp-ovn-4.6&grid=old shows failures.

Looking into a few of them, there appears to be a crashlooping pod in ns/openshift-ovn-kubernetes on most of the failures.  This is just an observation, I'm not a networking expert.

Alex mentioned this maybe fixed by https://bugzilla.redhat.com/show_bug.cgi?id=1880974 PR.
Keeping an eye on it.

Comment 4 Ben Bennett 2020-09-23 13:19:52 UTC

Useful sippy query for the job pass rates https://sippy.ci.openshift.org/detailed?release=4.6&endDay=1

Comment 5 Ricardo Carrillo Cruz 2020-09-23 13:20:41 UTC

It seems the pass rate has gone up?

https://sippy.ci.openshift.org/detailed?release=4.6&endDay=1

The PR from that related BZ landed, so hopefully that fixed the issue.

Comment 6 Ben Bennett 2020-09-24 17:34:36 UTC

GCP CI is looking a lot more stable.  I think the referenced fixes solved the problems.

Thanks all!

Comment 7 Anurag saxena 2020-09-24 17:47:05 UTC

Yep, recent various GCP installations looks okay to QE as well.

Comment 9 Anurag saxena 2020-09-24 18:49:00 UTC

Verifying based on comment 7
