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.
People I have talked to, who have grid-computing requirements,
generally avoid GFS (because of the complexity) and choose NFS.
Do you have concurrent writes to the same file from different nodes?
How many nodes do you have?
There are products tailored for this scenario (Isilon, Panasas)....

Good questions:
1) Do you have concurrent writes to the same file from different nodes?
1a) No
2) How many nodes do you have?
2a) 3 to start, probably won't go beyond 12
I appreciate alternative ideas to NFS. NFS could possibly introduce
performance issues (comments here appreciated). The majority of the
system is write. I would say 80%.
I suspect under that kind of a mostly-write load, NFS might actually
outperform GFS.
