Might try that, but I still need NFS for other systems and having used it for almost 30 years am a bit used to it ! Actually I haven't really had any real problems with NFSv4 under F13 or F14 both at work and home (each network one server and about 6 clients mounting /home and /data). The only real issue has been performance over an OpenVPN connection over ADSL, but that is not too surprising (although an ls -l takes significantly longer that it really should) and this performance issue when writing multiple files. Does gluserfs support client side file and attribute caching (cachefilesd is used with NFS) ? I use that with NFS over the OpenVPN/ADSL link which helps a bit (although I think it should work much better than it actually does).
