> 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.
