6 nodes but only 5 reasons reported

Upstream fix: https://github.com/kubernetes/kubernetes/pull/93355

Comment 2 Jan Chaloupka 2020-08-12 11:23:39 UTC

The upstream fix is not yet in openshift/kubernetes:release-4.6 branch which is currently rebased to 1.19 rc2.
It is part of 1.19 rc3. Waiting for the next rebase until it gets to 4.6. Once done, we can clone this to 4.5 and fix it there.

Comment 3 Jan Chaloupka 2020-08-12 11:25:44 UTC

4.5 PR https://github.com/openshift/origin/pull/25407

Comment 4 Jan Chaloupka 2020-08-24 14:23:47 UTC

Rama, no need to test this issue. It's mainly for backporting master fix to 4.5 so we can further debug flaking/failing e2e tests.

Checked log from : https://search.ci.openshift.org/?search=Unable+to+schedule&maxAge=48h&context=1&type=junit&name=&maxMatches=5&maxBytes=20971520&groupBy=job. 

Can't reproduce the issue now. Will move to verified.
