...and it's repeatable for me. I just umounted the two clients, killed
the server daemons and restarted glusterfs again, did a copy and got
similar results. First I copied a single file - and that worked fine.
Then I started a "rsync -a /etc/ /mnt/glusterfs/newDir" - and killed it
off. Then I did a "find /mnt/glusterfs/newDir -exec cat..." to ensure
both clients should be in sync - and they aren't???

I see a whole bunch of these in the glusterfsd.log file of the server
with the *larger* number of files

I think they are ignorable - they appears to all refer to symlinks - but
I'll mention them anyway.
