Well, I am having a heck of a time wrapping my head around how
clustering and gfs are related.  My application is an N+1 type of
configuration (grid computing).  I don't need any application
clustering that cluster suite offers.  I just need a file system that
they can all mount in read/write.  I might just have to get a couple
of RHEL5 boxes up and going to fully understand this.  Is cluster
suite and gfs included in RHEL5? Or how does that work?
