If the qtree has NTFS security style and if the CIFS user maps the qtree, then the mapped drive will be 1G in size under Windows. However on UNIX, the NFS mount of the qtree will still show the full size of the volume when a user quota is set. And rquota must be enabled on the controller side to check the user quota from the NFS client.
