A colleague just sent me this link: See DCF 1497567: Allocation and use of scratch and predefined FILE storage pool volumes http://www-01.ibm.com/support/docview.wss?uid=swg21497567
By the way, keep in mind that at least on some appliances, the NFS-mounted filespace "used/remaining space" attributes apply to the entire appliance filesystem, no matter which directory you query. As the platforms improve, some sort of quota system will probably be provided. Although whether it apply to pre-compressed/deduped or post-compressed/deduped numbers is a good question. How to allocate directories among devclasses is becoming a more interesting topic as NFS-mounted dedup appliances become more prevalent. Some resources are tied to devclasses, such as mountpoints, that would require some consideration.

I've checked everywhere I can think of and the most I can find is comments that TSM is free to pick any dir to create a new scratch vol in. Assuming lots of free space in multiple directories specified for one dev class type file, how does TSM pick which dir to create a file dev in? What I'm interested in is one of those "what if" questions. If you have a file dev class (NFS) on a dedup box and its getting full. So you purchase a new box, set it up, and add it to the devclass as an extra directory. You now have two directories. If one is full TSM will use the other, but if both have freespace I'm curious how TSM decides which to use. Just curious . . .
