-##### 2.4 Modifying MountOptions in Storageclass and PersistentVolumes
-
-CephCSI, starting from release v3.9.0, will pass the options specified in the
-StorageClass's `MountOptions` during both `NodeStageVolume` (kernel cephfs or
-ceph-fuse mount operation) and `NodePublishVolume` (bind mount) operations.
-Therefore, only common options that is acceptable during both the above
-described operations needs to be set in StorageClass's `MountOptions`.
-If invalid mount options are set in StorageClass's `MountOptions`
-such as `"debug"`, the mounting of cephFS PVCs will fail.
-
-Follow the below steps to update the StorageClass's `MountOptions`:
-
-- Take a backup of the StorageClass using
-  `kubectl get sc <storageclass-name> -o yaml > sc.yaml`.
-- Edit `sc.yaml` to remove the invalid mount options from `MountOptions` field.
-- Delete the StorageClass using `kubectl delete sc <storageclass-name>`.
-- Recreate the StorageClass using `kubectl create -f sc.yaml`.
-
-Follow the below steps to update the PersistentVolume's `MountOptions`:
-
-- Identify cephFS PersistentVolumes using
-  `kubectl get pv | grep <storageclass-name>`.
-- and remove invalid mount options from `MountOptions` field
-  in the PersistentVolume's using `kubectl edit pv <pv-name>`.
-
 we have successfully upgraded cephfs csi from v3.8 to v3.9
