CentOS6.4, X86_64

Description

I found some problems of lustre_rsync,
1. Do follow shell scripts:
#!/bin/sh

pushd /mnt/lustre
mkdir racer
mkdir racer/11
mkdir racer/13
mv racer/13 racer/14
mkdir racer/14/14/
mv racer/14 racer/11/

popd

2. use lustre_rsync to sync the files, then will cause difference between source and target directories.

I found it will be orphan node under .lustrerepl

Ah, sorry, maybe my patch is misleading your guys.
I think there are some problems in the lustre_rsync, and my patch just fixed one problem.

This script still will cause another problem, that data are difference between source and target directory:
#!/bin/sh
pushd /mnt/lustre
mkdir racer
mkdir racer/11
mkdir racer/13
mv racer/13 racer/14
mkdir racer/14/14/
mv racer/14 racer/11/
popd

And, i did not find the root cause, anyone can help me?
