> After HDFS-11274, we will not trigger checking all datanode volumes upon IO
> failure on a single volume. This makes the original implementation
> DataNode#checkDiskErrorAsync and DatasetVolumeChecker#checkAllVolumesAsync()
> not used in any of the production code.
> This ticket is opened to remove these unused code and related tests if any.
