> MiniDFSCluster hardcodes the number of directories per volume to two. Propose 
> removing the hard-coded restriction.
> It would be useful to limit the capacity of individual storage directories 
> for testing purposes. There is already a way to do so for SimulatedFSDataset, 
> we can add one when using real volumes.
