> Hot swapping data volumes might fail. The user should be able to fix the
> failed volumes and disks, then ask the {{DataNode}} to retry the previously
> failed volumes.
> To attempt to reload the failed volume again on the same directory, this
> failed directory must not be presented in the {{Configuration}} object that
> {{DataNode has}}. Therefore, it should only put successfully loaded volumes
> into the {{Configuration}} object.
