\uD83E\uDD14 Problem
MongoDB pods cannot start due to persistent volume mounting error.
\uD83C\uDF31 Solution
Configure MongoDB to use a new persistent volume.
Run command: kubectl edit statefulset mongo -n <onelist namespace>
Change volumeMounts.name to a different value. For example: mongo-persistent-volume-2. Save the change.
MongoDB pods will restart. A new persistent volume will be created and mounted by the new pods.
