> With really large clusters, the basic DiskValidator isn't sufficient for some
> of the less common types of disk failures.
> Look at a new DiskValidator that could do one or more of the following:
> - Add new tests to find more problems
> - Add new metrics to at least characterize problems that we haven't predicted
