That was useful I have not had the time to do any testing but I do see a
few issues. What if the disks is of different size ??

The numbers of slots (there is one volume per slot) is globally defined.
so a 2T disk and a 1T disk is getting the same amount. The volume size
is then specified in the pool or storage config and they can't
differentiate the two different sized disks. 

So you can not have different sized disks or am I reading it wrong?
