Unless I am gravely mistaken, the filer reserves some space for Snapshots, with the result that (if that space is not filled) deleting a file *does* make space available immediately. I believe the default space allocation for snapshots is 20% of the the disk. If the snapshot space is filled, then snapshots take up space on the visible disk and you are in the situation you describe.
We run consistently at 98% of capacity, and I have never run into a situtation where space could not be recovered merely by deleting a file.
Of course if you need a lot of space, you may have to find a way to delete a snapshot.

List,
Is there any way to cheat with snapshots so that data in them can be deleted?
I have stupidly let a volume on my filer grow to capacity and want to free up space my moving files to another volume, if I just move the files I will get no gain in free disk space because the files will exist in the snapshot right?
Could I cheat this by taking a snapshot of the volume before I delete the files then delete the snapshot after the file are deleted?
