> 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.
