Storage Object in Use Protection
The purpose of the storage object in use protection feature is to ensure that PVCs, in active use by a Pod, and PVs, that are bound to PVCs, are not removed from the system, as this may result in data loss. If a user deletes a PVC in active use by a Pod, the PVC is not removed immediately. PVC removal is postponed until the PVC is no longer actively used by any Pods. Also, if an admin deletes a PV that is bound to a PVC, the PV is not removed immediately. PV removal is postponed until the PV is no longer bound to a PVC.
