Kubernetes run mariadb pod use pv hostpath. Occur File system loop detected in '/var/lib/mysql'

Question

I have used minikube tunnel connect local folder to mount /mnt/data/mysql .

I used yaml below...

mariadb-data-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mariadb-data-pv-volume
spec:
  storageClassName: stardard
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  persistentVolumeReclaimPolicy: Retain
  accessModes:
    - ReadWriteOnce # 單一Pod 讀/寫
  hostPath:
    path: /var/lib/mysql
    type: "DirectoryOrCreate"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mariadb-data-pv-claim
spec:
  storageClassName: stardard
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi 

kubernetes-mariadb-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mariadb-deployment
spec:
  selector:
    matchLabels:
      app: dev
  replicas: 1
  minReadySeconds: 5
  template:
    metadata:
      labels:
        app: dev
    spec:
      containers:
      - name: mariadb
        image: mariadb:10.4.31
        resources:
          limits:
            memory: "512Mi"
            cpu: "1500m"
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "myP@ssword"
        ports:
        - containerPort: 3306
        volumeMounts:
        - name: mariadb-persistent-storage
          mountPath: /mnt/data/mysql
      volumes:
      - name: mariadb-persistent-storage
        persistentVolumeClaim:
          claimName: mariadb-data-pv-claim
          

then execute command

kubectl apply -f .\persistents\mariadb-data-pv.yaml
kubectl apply -f .\deployments\kubernetes-mariadb-deployment.yaml

Question: First time init the pod is work. And create a database named "sampledb". I can see the container /var/lib/mysql data has transfer to my local computer /mnt/data/mysql directory.

But When I used kubectl delete -f .. try to run pod again. It has error below:

[Note] [Entrypoint]: Entrypoint script for MariaDB Server 1:10.4.31+maria~ubu2004 started.
find: File system loop detected; ‘/var/lib/mysql/hwuc’ is part of the same file system loop as ‘/var/lib/mysql/’.

Has anyone experienced this problem or has any advice on it?

I have try update mariadb version to 10.5.22 and 10.3.38 still get same error.

-------- Update 2023.11.3 --------

Solve this problem.

found when used minikube mount /mnt/data:/mnt/data cause this error.
