>     When DirectoryScanner used diff ScanInfo to check and update with memBlock, i found the LocalReplica#updateWithReplica only update the diskfile path but without replicaInfo's volume. And may be the memblock ' volume is diff with the diskfile path before directory scan, so i think need to update the volume meanwhile,so the replicaInfo's meminfo is consistent with disk storage。The relation code as follows:
> {code:java}
> public void updateWithReplica(StorageLocation replicaLocation) {
>     // for local replicas, the replica location is assumed to be a file.
>     File diskFile = null;
>     try {
>       diskFile = new File(replicaLocation.getUri());
>     } catch (IllegalArgumentException e) {
>       diskFile = null;
>     }
>     if (null == diskFile) {
>       setDirInternal(null);
>     } else {
>       setDirInternal(diskFile.getParentFile());
>     }
>   }
> {code}
> Thanks all!
