Create the nfs pv for fulfilling the requirement.

### PV

```auto
kind: PersistentVolume
metadata:
  name: nfs-home-pv
  labels:
    app: mission-control
    id: jfmc-es-pv
    type: nfs-volume
spec:
  capacity:
    storage: 50Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  nfs:
    ####################################
    # MUST SET ACTUAL NFS SERVER IP HERE
    server: 192.168.126.151
    ####################################
    path: "/home"
    readOnly: false
---

### PVC
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: nfs-home-pvc
  labels:
    app: mission-control
    type: nfs-volume
spec:
  accessModes:
