My google/support searches are not turning up information about NTFS sparse file attribute support on OneFS.

I have found info on how to create a sparse file using the linux dd command and this worked.  The file is sparse and I can see the file size the file system reports and how much disk space the file is actually taking.  However accessing this file via SMB client the file takes up more disk space than the file size.

I have tried copying a sparse file from a windows machine to the share on the Isilon cluster (7.1.0.5) and the file is copied taking up the full amount of space and the sparse attribute (P) is not set on the file on the Isilon cluster.  I can successfully copy the same sparse file to shares on NetApp ONTAP 7, 8.x Cluster VSM, VNX5300 and VNX5200.  All of these will show the sparse attribute on the destination file.  The VNX5200 however will show the disk usage the same as the file size even though the sparse attribute is set.

So the question is how can I get the NTFS file attribute set for a sparse file?  Any ideas or links to docs about this?  If possible what actually is supported for NTFS attributes would be helpful too like NTFS encryption, compression, etc...
