- The driver does not provide read-only access level for shares.
- Assume that share S is exported through Gluster NFS, and tenant machine T
has mounted S. If at this point access of T to S is revoked through
`access-deny`, the pre-existing mount will be still usable and T will still
be able to access the data in S as long as that mount is in place.
(This violates the principle *Access deny should always result
in immediate loss of access to the share*, see
