Hi Daniel,

Thanks for the answer!

I would like to setup my storage cluster with actual partition (2TB) and 
after setup the same boxes with one big 10TB partition on each box. My 
goal is to compare the two solutions in terms of performance.

I have a supplementary question: Is it possible to configure glusterfs 
with more than one partition in a brick? If yes, what's the syntax to use?
