Edit:

I've solved this issue. Rancher is a containerized deployment of kubernetes. Please see this answer

Original Questions:

I tried to use local persistent volume with kubernetes 1.13. But it always told me the local path not exist.

Here are my specifications:

### pv.yml
apiVersion: v1
kind: PersistentVolume
metadata:
  name: sawtooth-local-pv-000015
  namespace: sawtooth
spec:
  capacity:
    storage: 10Gi
  accessModes:
  - ReadWriteOnce
  storageClassName: local-storage-normal
  local:
    path: /mnt/disks/sdb1
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - sawtooth-4
## pvc.yml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: sawtooth-local-pvc-000015
  namespace: sawtooth
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: local-storage-normal
## sc.yml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage-normal
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
# Supported policies: Delete, Retain
reclaimPolicy: Retain

When I tried to create a pod using the pvc, it always give me this error:

MountVolume.NewMounter initialization failed for volume "sawtooth-local-pv-000015" : path "/mnt/disks/sdb1" does not exist

Here's some infomation about the disks:

## fdisk -l
Device     Boot Start       End   Sectors Size Id Type
/dev/sdb1        2048 125829119 125827072  60G 83 Linux

## /etc/fstab
/dev/sdb1        /mnt/disks/sdb1  ext4    defaults   0 0
