Hi Shyam/Madhu,

Yes I am hitting this bug during 4.13 testing, and it remains a 4.13 blocker as we have now reproduced it.

I reported it here https://bugzilla.redhat.com/show_bug.cgi?id=2160034#c62 thinking it's a different issue, but everything looks good at RBD level.
Pls check the bug and following comments on it for further updates.

Reverting needinfo and pls note that we have a live cluster in the same shape for debugging. So we won't be able to work on reproducing this bug again in the future.

All the logs are attached to the same comment.

I am providing C1 details where the cleanup has stuck.

It looks like the ApplicationSet operator didn't clean up the App when requested. The workload remained in the old primary waiting for the App to be deleted.
The PlacementDecision was updated as expected;
```
oc get placementdecision -n openshift-gitops      admin-placement-decision-1 -o yaml
apiVersion: cluster.open-cluster-management.io/v1beta1
kind: PlacementDecision

The ApplicationSet status show an error:
```
status:
    conditions:
    - lastTransitionTime: "2023-04-03T12:33:30Z"
      message: Successfully generated parameters for all Applications
      reason: ApplicationSetUpToDate
      status: "False"
      type: ErrorOccurred
    - lastTransitionTime: "2023-04-03T12:33:30Z"
      message: Successfully generated parameters for all Applications

      message: ApplicationSet up to date
      reason: ApplicationSetUpToDate
      status: "True"
      type: ResourcesUpToDate
```

Next is to check the ApplicationSet/Application operators logs to figure out what happens...
