Description Madhu Rajanna 2021-09-23 10:49:56 UTC 
Description of problem (please be detailed as possible and provide log
snippests):

VolumeReplication statuc condition "Degraded" never moves to "False" when recovering from a split-brain of rbd image.


Version of all relevant components (if applicable):

4.9

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?

Yes



If this is a regression, please provide more details to justify this:


Steps to Reproduce: 
 (these are the reproducer steps without Ramen)

* Create PVC in cluster1 (using rbd as the provisioner

* Create VR pointing to PVC above and the state as "Primary" (in cluster1)
* Ensure image on both clusters in rbd are present (using toolbox)
* Copy PV backing PVC on cluster1 to cluster2
* Create the same PVC on cluster2
* Ensure it is bound to the PV
* Create VR on cluster2, pointing to the PVC above, and the state as "Primary"
* Update VR on cluster1 to "Secondary"

Wait for VR conditions to reach the state (Completed:True; Resyncing:True; Degraded:False, for the current generation number (usually 2 in this test case))
VolRepl does not change "Degraded" to False at all, it remains "True"
Checked backend ceph image mirror status (or image info) on cluster1 and image reaches "state: up+replaying"


Actual results:

The degraded condition is not setting to False once split-brain is corrected


Expected results:

The degraded condition is set to False once split-brain is corrected
