Description

I had a directory that contained two files (one is a hardlink of another):

# ls -il /hardlink/
total 120
163865 -rwxr-xr-x 2 root root 53400 Nov 11  2010 ed
163865 -rwxr-xr-x 2 root root 53400 Nov 11  2010 red

After copying the directory to a Lustre filesystem:

cp -a /hardlink /mnt/lustre/

Running lustre_rsync hit the following errors:

# lustre_rsync --source=/mnt/lustre/ --target=/mnt/backup/ --mdt=lustre-MDT0000 --user=cl1 --statuslog lustre_rsync.log --verbose
