Description Ben Parees 2021-07-02 21:15:16 UTC
Description of problem:

https://prow.ci.openshift.org/job-history/gs/origin-ci-test/logs/release-openshift-origin-installer-old-rhcos-e2e-aws-4.9

is pretty consistently failing due to:

fail [github.com/openshift/origin/test/extended/util/disruption/disruption.go:190]: Jul  1 16:24:28.261: Unexpected alerts fired or pending during the upgrade:

alert ClusterMonitoringOperatorReconciliationErrors fired for 60 seconds with labels: {severity="warning"}


example job:
https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/release-openshift-origin-installer-old-rhcos-e2e-aws-4.9/1410608470004076544


can be seen in ci-search that this is failing most of our "old-rhcos" job runs:
https://search.ci.openshift.org/?search=ClusterMonitoringOperatorReconciliationErrors&maxAge=336h&context=1&type=bug%2Bjunit&name=release-openshift-origin-installer-old-rhcos-e2e-aws-4.9&excludeName=&maxMatches=5&maxBytes=20971520&groupBy=job


Note that this job uses v4.8 nodes with v4.9 control plane, which may be part of the issue, but I also see there have been other bugs in this space that were marked resolved recently, e.g.:

https://bugzilla.redhat.com/show_bug.cgi?id=1932624

Version-Release number of selected component (if applicable):
4.9

How reproducible:
failing semi regularly.


Actual results:
Alert fires for 60s during upgrade

Expected results:
Alert should not fire during upgrade (we expect no warning alerts during upgrades)


It may be necessary to configure this alert w/ a higher delay period before it fires, if there is not a fundamentally fixable flaw in the operator itself.
