Description Nikolaos Leandros Moraitis 2020-07-23 10:04:28 UTC 
test:
[sig-cli] oc adm must-gather runs successfully 

is failing frequently in CI, see search results:
https://search.svc.ci.openshift.org/?maxAge=168h&context=1&type=bug%2Bjunit&name=&maxMatches=5&maxBytes=20971520&groupBy=job&search=%5C%5Bsig-cli%5C%5D+oc+adm+must-gather+runs+successfully


FIXME: Replace this paragraph with a particular job URI from the search results to ground discussion.  A given test may fail for several reasons, and this bug should be scoped to one of those reasons.  Ideally you'd pick a job showing the most-common reason, but since that's hard to determine, you may also chose to pick a job at random.  Release-gating jobs (release-openshift-...) should be preferred over presubmits (pull-ci-...) because they are closer to the released product and less likely to have in-flight code changes that complicate analysis.

FIXME: Provide a snippet of the test failure or error from the job log

A possible fix is in the works, which is changing the tests and making it more resilient.

PR landed.

I've filed bug 1861201 for the new-ish 'oc adm must-gather runs successfully for audit logs' flake.

Seems the fixed PR involved new issue, the test : "[sig-cli] oc adm must-gather runs successfully with options" is failing frequently in CI 

 Always see error:

fail [github.com/openshift/origin/test/extended/cli/mustgather.go:198]: Expected success, but got an error:
