# Managing NFS Mount Options

NFS mount options that VAST CSI Driver uses when mounting a volume for a PVC can be set as follows:

- Per storage class

Supply mount options for a particular storage class using the `mountOptions` parameter in the VAST CSI Driver's [Helm chart configuration file](/develop/docs/en/create-a-helm-chart-configuration-file-for-vast-csi-driver-2-5) or the `mount_options` parameter in the Kubernetes [YAML configuration file](/develop/docs/en/using-storage-classes-2-5).
- Per host

Supply mount options in a host-specific NFS mount configuration file (`.conf`) located in the `/etc/nfsmount.conf.d` directory.

> [!NOTE]
> Note
> 
> Ensure that the underlying OS of the worker nodes supports use of the `/etc/nfsmount.conf.d` directory for setting mount options (see `man nfsmount.conf` ).

If both storage class-specific and host-specific options are specified, storage class-specific options take precedence.

To make VAST CSI Driver ignore host-specific mount options, set the `propagateHostMountOptions` parameter to `false` in the driver's Helm chart configuration file:

```plaintext
node:
  propagateHostMountOptions: false
```
