Well, About 3 gig is other partions, and it appears to me that the other 
7G is lost to making the raid device and various overheads (though that 
sure seems excessive).

The odd thing is that I'm sure I created the LV at a full 100% of the 
disk...

I did as you suggested, and used "resize_reiserfs".  It seems better, 
but we shall see if it changes on me again...
