The last time I evaluated GlusterFS, it did not support 
graceful server disconnection/rebooting (i.e. clients with 
open files will see errors instead of blocking).  While it 
would be awesome of this were simply "fixed" at the 
GlusterFS level, if the NFS xlator provides this 
functionality it would be a big win.  This feature is the
single feature keeping me from using GlusterFS to this 
day.  I look forward to either of theses solutions so that
I could use GlusterFS,
