> 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.
