1. While creating pv with host path:

ubuntu@ip-172-18-6-23:~/configs$ kubectl create -f pv_4.yaml 
The PersistentVolume "recyle-pv4" is invalid: metadata.annotations.volume.beta.kubernetes.io/mount-options: Forbidden: may not specify mount options for this volume type

2. While creating a AWS EBS pv:

ubuntu@ip-172-18-6-23:~/configs$ cat pv_mo.yaml 
apiVersion: "v1"
kind: "PersistentVolume"
metadata:
  name: hekumar-discard
  annotations:
    volume.beta.kubernetes.io/mount-options: "discard"
spec:
  capacity:
    storage: "10Gi"
  accessModes:
    - "ReadWriteOnce"
  awsElasticBlockStore:
    fsType: "ext4"
    volumeID: "vol-f37a03aa" 

It worked.

3. Updating a PV with unsupported mount options:

ubuntu@ip-172-18-6-23:~/configs$ kubectl replace -f pv_4.yaml 
The PersistentVolume "recyle-pv4" is invalid: metadata.annotations.volume.beta.kubernetes.io/mount-options: Forbidden: may not specify mount options for this volume type
