You can answer part of this question by looking at the infrastructure requirements
and performance profile of each filesystem (for example, AFS filesystem cloning
is a big help, but AFS can be a lot to manage; do you need snapshot, etc.).
I've played with GFS before and found you really do need the fibre and attached
storage to get the real benefits.

Sometimes you don't even need a special filesystem. If you want to create a
parallel build cluster it might be good enough to use ccache and distcc.

What do you want to do with this filesystem?
