> When DirectoryScanner doing the scan function, it holding the dataset to diff
> the block info between memory and disk.But it do a lot of disk operation

> Once the dataset is locked,heartbeat thread and all DataXceiver thread would
> be blocked.
> So,such disk operation should move to the async disk scan
