With unified AFR (and AFR for namespace), even du doesn't work properly
with NFS reexport:
du -sk usr*
263152 usr0
223612 usr0-copy
277536 usr1
du: cannot access `usr1-copy/share/perl/5.8.8/unicore/lib/gc_sc/\a': No
such file or directory
du: cannot access `usr1-copy/include/bits/\f': No such file or directory
du: cannot access `usr1-copy/include/bits/"P\001': No such file or
directory
202304 usr1-copy
du -sk usr* (from GlusterFS client)
406684 usr0
406708 usr0-copy
406684 usr1
406716 usr1-copy
Thanks,
Brent

NFS reexport of a unified GlusterFS seems to be working fine as of TLA 409.
I can make identical copies of a /usr area local-to-glusterfs and
glusterfs-to-glusterfs, hardlinks and all. Awesome!
However, this is not true when AFR is added to the mix (rsync
glusterfs-to-glusterfs via NFS reexport):

Any ideas? Meanwhile, I'll try to track it down in strace (the output will be
huge, but maybe I'll get lucky)...
Thanks,
