How to persist data for all users that are chroot into their home?

Question

I have the following manifest where I deploy and persist SFTP data for users:

---
apiVersion: v1
kind: Secret
type: Opaque
metadata:
  name: sftp-secrets
  labels:
    name: sftp-alpine
  namespace: mynamespace
data:
  SFTP_PASSWORD_1: X
  SFTP_PASSWORD_2: Y
  SFTP_PASSWORD_3: Z

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: sftp-alpine
  namespace: mynamespace
  labels:
    name: sftp-alpine
spec:
  replicas: 1
  selector:
    matchLabels:
      name: sftp-alpine
  template:
    metadata:
      labels:
        name: sftp-alpine
    spec:
      containers:
        - name: sftp
          image: sftp:v01
          imagePullPolicy: Always
          args: [
            "user1:$(SFTP_PASSWORD_1):1001:100:data", 
            "user2:$(SFTP_PASSWORD_2):1002:101:data",
            "user3:$(SFTP_PASSWORD_3):1003:102:data"
            ]
          ports:
            - containerPort: 22
          envFrom:
          - secretRef:
              name: sftp-secrets
          volumeMounts:
           - mountPath: /home/user1/data
             name: config-nas
          livenessProbe:
            tcpSocket:
              port: 22
          readinessProbe:
            tcpSocket:
              port: 22
          resources:
            requests:
              cpu: 100m
              memory: 500Mi
            limits:
              cpu: 500m
              memory: 2Gi
      volumes:
      - name: config-nas
         persistentVolumeClaim:
          claimName: pv-claim

When I deploy it, SFTP server works well. For one user his data are persistent.

I would like to do it for all users, persist data for all users that have data in their folder. I tried with mountPath "/home" but my SFTP doesn't work after this modification. It connects and SFTP disconnect immediately.

How can I do to persist data for all users ?
