If you are this confident in NFS, you have had a better experience with 
it than I have.  I have had fileservers with CPU lockups just as 
described in the log in this thread.  They started after I updated the 
kernel thinking it would be harmless!  NFS does *not* just work.  There 
have been (and still are) bugs, incompatibilities between systems that 
should work, and (biggest problem) baked-in bad design decisions in 
NFS.  Feel free to argue that it does work more often than GlusterFS, or 
that it is less buggy.  That is hardly surprising considering how much 
more it is used, how much longer it has been around, and how much less 
it does.
