Use NFS, but mount through storage vendor’s container storage interface (CSI).
The Container Storage Interface is what exposes the storage to OCP/K8s. So, when you ask for storage the CSI provisions the PV that the container uses.
Pod à PV/PVC à CSI à Storage
The “virtual” mapping to the file system are effectively mount points for the pod. We have seven for the CPE (although three are now unused).
The one named “cpe-filestore-pvc” targets usage with file-based content storage.
