I am using three nodes kubernetes cluster and have created pv and pvc with following yaml.

1. pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata: 
  name: pv01
spec:
  accessModes:
  - ReadWriteOnce
  volumeMode: Filesystem
  capacity:
    storage: 1Gi
  storageClassName: local-storage
  local:
    path: /mnt/data
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - kworker1

2. pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc01
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 100Mi
  storageClassName: local-storage
  volumeName: pv01

After creating the pv anc pvc, trying to create a pod, which uses the pvc but it ramined in pending state.

3. pod.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc01
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 100Mi
  storageClassName: local-storage
  volumeName: pv01

why it is in pending state.
