I did look at those, and even tried to Google for examples, but my reading 
of them is that you get to choose which of {header, index, cache, expunge, 
squat} you want on your metapartition, but you can only have one shared 
metapartition per partition. So I can't do what I want, ie put the squat 
files on a different volume to the other files if I also want to use a 
metapartition for them.

Am I missing something?
