Thanks for the various answers and suggestions.

To answer the questions:
> Why use GFS in a read-heavy environment?  Why not use plain old NFS?
It is neither READ nor WRITE heavy. The app binaries will be loaded
and stay there till the end of the day. Do not want to go NFS route
since the NFS server is single point of failure.

Haven't looked into NFS + cachefs.

I'm actually thinking of going GFS2.

The bottom line is, I want to have only ONE app binary partition so that:
1. I'm 100% sure the servers are always running the same code.
2. Less maintenance; just upgrade the app files once when there is a
new version of app to be installed.
3. No single point of failure - Can't afford the servers hanging due
to NFS server going south.
4. Only ONE partition to back up/restore.

Bottom line, I'm trying to come up with a robust and low maintenance
design. If there are better solutions than GS2 based cluster file
system I'm all ears and flexible. Thanks in advance.
