 NFS has two additional options that aren't relevant when using iSCSI:
 
 * ``unixPermissions`` - this controls the permission set for the volume itself. By default the permissions will be set to ``---rwxr-xr-x``, or in numerical notation ``0755``, and root will be the owner. Either the text or numerical format will work.
-* ``snapshotDir`` - setting this to ``false`` will make the .snapshot directory invisible to clients accessing the volume. The default value is ``true``, meaning that access to snapshotted data is enabled by default. However, some images, for example the official MySQL image, don�t function as expected when the .snapshot directory is visible, so turning it off may be needed.
