Description Hongkai Liu 2020-10-01 19:58:27 UTC

Description of problem:
During the upgrade from 4.5.13 to 4.5.14, our blackbox probe failed over 1 min.
The upgrade is successful.

Here is the alert:

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


How reproducible:
It is the 2nd time it happened to buildl01 (an OCP cluster in CI infra).

Is it expected behaviour?

I will upload must-gather later.

Is the probe a part of OpenShift? If not, how does it look like?

Comment 4 Oleg Bulatov 2020-10-22 11:47:58 UTC

Apparently we never checked how the registry behaves during upgrades. Moving to Jira for further investigation: https://issues.redhat.com/browse/IR-152
