Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
yes, apps on running managed cluster should not be deleted

Is there any workaround available to the best of your knowledge?
no

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
4

Can this issue reproducible?
not sure

Can this issue reproduce from the UI?


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

Steps to Reproduce:
1. Create 4 OCP clusters such that 2 hubs and 2 managed clusters. And one stretched RHCS cluster.
   Deploy cluster in such a way that
	zone a: arbiter ceph node
	zone b: c1, h1, 3 ceph nodes
	zone c: c2, h2, 3 ceph nodes
2. Configure MDR and deploy 20 applications on each managed clusters
3. Initiate a backup process, such that the active and passive hubs are in sync
4. Made zone b down, ie c1, h1 and 3 ceph nodes
5. Initiate the restore process on h2
6. Restore succeeded in new-hub, dr policy on h2 in validated state
7. Check applications on c2 cluster


Actual results:
Applications present on c2 managed cluster are deleted after hub recovery

Expected results:
Applications on c2 managed cluster should present and in running state after hub recovery.


Additional info:
Had validated the status of apps on c2 some time before hub recovery:

This fix did not cause the CVP issue, patch to be included in 4.12.5.

Comment 16 krishnaram Karthick 2023-06-28 06:07:35 UTC

Bug still in assigned state at the time of 4.12.5 finalization. Moving the bug to 4.12.6.

Comment 24 krishnaram Karthick 2023-09-28 07:21:01 UTC

Verification of this bug at 4.14 is still not complete. 
Moving the bug to 4.12.10 release for verification.

Comment 25 krishnaram Karthick 2023-10-30 09:42:33 UTC

We also need fix for https://issues.redhat.com/browse/ACM-7115 to verify this bug and the fix is not backported on to ACM 2.7 z streams. 
Moving the bug out to 4.12.11

Comment 26 krishnaram Karthick 2024-01-02 14:01:59 UTC

4.12.11 content finalization was complete and this fix was not part of it. 
moving the bug to next z stream.

Comment 28 krishnaram Karthick 2024-02-15 11:48:10 UTC

Harish - Given that hub recovery won't be supported in z streams for MDR, Can we close this bug?
