Description of problem (please be detailed as possible and provide log snippests): During upgrade from OCS 4.5 to 4.6 there is a brief outage for the object store until the upgrade is completed, between the time when the RGW service is updated with some new labels and the RGW pods are updated. For most clusters this may only be a matter of seconds. Version of all relevant components (if applicable): OCS 4.5 upgrade to OCS 4.6 Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? No Is there any workaround available to the best of your knowledge? Wait for the upgrade to complete Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? 1 Can this issue reproducible? Yes Can this issue reproduce from the UI? Yes If this is a regression, please provide more details to justify this: Yes, it's a regression in OCS 4.6. A new label was mistakenly added to a matchSelector on the RGW service, which causes the outage. Steps to Reproduce: 1. Install OCS 4.5 2. Start an object (s3) workload 3. Upgrade to OCS 4.6 Actual results: The object workload fails briefly while the rgw pods are updating. Expected results: Object workloads should continue working while the rgw pod is updating. Without this bug, the workloads can continue since there are two rgw pods and one will serve requests while the other one is updating. Additional info: This was found by an upstream user and reported in this issue: https://github.com/rook/rook/issues/6718
The fix has already been made upstream and is very low risk, I would like to see it accepted to 4.6.z.
Moving it back to 4.6.0 as decided in pgm meeting. Travis, please merge the backport PR to 4.6
Moving to VERIFIED based on OCS 4.6 RC7 regression cycle automation runs
