I'm using Helm to deploy postgres on Kubernetes cluster. I create a persistent volume and a persistent volume claim:

pv.yaml:

    apiVersion: v1
    kind: PersistentVolume
    metadata:
      name: task-pv-volume
      labels:
        type: local
    spec:
      storageClassName: manual
      capacity:
        storage: 10Gi
      accessModes:
        - ReadWriteMany
      hostPath:
        path: "/mnt/data"

pvc.yaml:

    apiVersion: v1
    kind: PersistentVolumeClaim
    metadata:
      name: task-pv-claim
    spec:
      storageClassName: manual
      accessModes:
        - ReadWriteOnce
      resources:
        requests:
          storage: 8Gi

and run helm with command:

helm install my-release stable/postgresql --set persistence.existingClaim=task-pv-claim

but Pods is in state CrashLoopBackOff. Logs of the pod say:
