> Affects Versions: 2.6.0

>
> 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.
