### Upgrading CephFS
If existing cephfs storageclasses' `MountOptions` are set, please refer to
[modifying mount options](#24-modifying-mountoptions-in-storageclass-and-persistentvolumes)
section.
Upgrading cephfs csi includes upgrade of cephfs driver and as well as
kubernetes sidecar containers and also the permissions required for the
kubernetes sidecar containers, lets upgrade the things one by one

##### 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
