> When {{DataNode#checkDiskError}} found disk errors, it removes all block metadatas from
{{FsDatasetImpl}}. However, it does not removed the corresponding {{DataStorage}} and {{BlockPoolSliceStorage}}.

> The result is that, we could not directly run {{reconfig}} to hot swap the failure disks
without changing the configure file.
