Gluster users - Apr 2010 - 2.0.2 to 2.0.9, now missing files/directories?

I have two glusters, a production and test gluster. A while back, I upgraded the
test gluster from 2.0.2 to 2.0.9 with no problems. Both glusters are running
gentoo,
same version, same kernel. The client saw all of the files, everything worked. 

Over this weekend I upgraded the main production gluster, as we are trying to
get some
more speed and I was told by the gluster team some time ago to try out 2.0.9 to
cure
a few problems. I did the same exact upgrade that I did on the test gluster. 
Now that I am done, I can mount it fine and I get no errors in the logs,
however,
most (e.g. 85%) of my files are missing, or I get a "cannot access
/data/blah/blah no
such file or directory". The files exist on the server in the exported
directory,
but the client does not see some of them. I recall there was something I had to
do
to fix this perhaps... I can not recall what it is. 

Anyone have any ideas? (other than shutting down work tomorrow, ugh)
