Setting to force nss to issure a free/delete to disk when filedeleted

[markcasey]

Hi

Typically when I delete a file, (I believe that) nss like most other
filesystems sets a flag the it is deleted in the fat table, but doesn't
actually issue a delete.

Is there a way with nss to force it to issue an ISCSI delete or free
command when the file space is freed ?

Im not trying to scrub, which overwrites the data, but to free the blocks
on the underlying san

Thanks in Advance
