OpenShift Dedicated uses the Kubernetes persistent volume (PV) framework to allow cluster administrators to provision persistent storage for a cluster. By default, MongoDB is deployed using persistent volume claims (PVC). mongodb-persistent uses a persistent volume store for the database data which means the data will survive a pod restart. The mongodb persistent storage is not working like it's supposed to. This storage practice allows you to maintain application data, even if the application's pod fails.
