Mongo Persistence NOT Retaining Data on K8S Cluster After Reboot

Question

I have created my own k8s cluster using Kubeadm with two Ubuntu virtual servers - one master and one worker node. I also deployed a Springboot app with MongoDB persistence and it works absolutely fine. Below are the nodes in my k8s cluster

Below are the contents of my yaml file which creates storage class, persistence volume, persistence volume claim, mongo deployment and mongo service

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
   name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
allowVolumeExpansion: true
reclaimPolicy: Retain

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mongo-pv
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: local-storage
  hostPath:
    path: "/home/moviepopcorn/mongodb/data"
  nodeAffinity:
    required:
      nodeSelectorTerms:

          values: 
          - node1

apiVersion: v1

          ports:
          - containerPort: 27017 
          volumeMounts:
          - name: mongo-persistent-storage
            mountPath: /home/moviepopcorn/mongodb/data
        volumes:
          - name: mongo-persistent-storage
            persistentVolumeClaim:
              claimName: mongo-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: mongo-service
spec:
  selector:
    app: mongo
  ports:
    - protocol: TCP 
      port: 27017
      targetPort: 27017

Data stored from my Springboot into mongodb is not retained once I reboot the nodes in my k8s cluster. Could you please help me understand on what mistake I am doing?
