Can you include some comments here?  It's not clear which pool type has 
which values set.  Instead of using comments, you could define the pool 
type values in pool.py.  Then you could do something like:

ptype6['Type'] = LOGICAL_POOL  - this will make it easier to tell which 
type is which.

+                             ptype5, ptype6, ptype7 ]
I would use more descriptive names... instead of ptype1, use something 
like dir, fs, etc - that'll also make it more clear which dictionary 
belongs to a given pool.

This is a lot of indention.  Can some of this be moved out to a helper 
function?
