> 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!
