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

Facing issue while relocating logwriter(Statefulset) app from c2 to c1 managed cluster on MDR 4.13 setup. I applied the workaround to manually delete the terminating logwriter PVCs after initiating relocate, as mentioned here: https://bugzilla.redhat.com/show_bug.cgi?id=2118270#c27. But, PVCs are still stuck in terminating state(oc delete pvc command hangs).
