> Current implementation shuts DataNode down completely when one of the
> configured volumes of the storage fails.
> This is rather wasteful behavior because it decreases utilization (good
> storage becomes unavailable) and imposes extra load on the system
> (replication of the blocks from the good volumes). These problems will become
> even more prominent when we move to mixed (heterogeneous) clusters with many
> more volumes per Data Node.
