I found NFSv4 to be completely unusable on my F14 systems. I could never 
figure out where the problem was. It was unusable on my F14 clients when 
I had a F13 server, and once I upgraded the server to F14, my F13 
clients became unusable...

In desperation, I had to move to glusterfs, which fixed all my problems:

I've been very happy with it since the forced migration! It has a lot 
fewer oddities than NFS, and it handles sqlite/firefox file-locking just 
fine, unlike some (all?) NFS variants.
