Description of problem (please be detailed as possible and provide log
snippests):

Post relocation new PVC created on primary cluster for 2 of the apps "bb-cephsub"  and "cronjob-sub-ns".

Note that before performing failover and relocation we removed osd-0 disk from a host, zap it and add it back as a new OSD on the same host

Steps to Reproduce:
1. Deploy MDR cluster
2. Deploy all types of applications
3. Performed the RHCS procedure: removed osd-0 disk from a host, zap it and add it back as a new OSD on the same host
4. Once ceph all healthy, fenced c1 and tried the failover of the applications from c1 to c2
5. Then tried the relocation of all the applications


Actual results:
Post relocation new PVC created on primary cluster

Expected results:
Relocation should succeed

Additional info:
As mentioned by Shyam this might be race condition, as on same cluster few other application were able to failover and relocate successfully.

Details of the root cause can be found in the linked upstream PR.

The issue should have started around Dec-2023 when some changes were made in this area of code.
