Maybe this page could be worked up a little more with some information on this?

I apologize for not knowing, Im not sure who all does the examples or
if its one person or what. Could the person(s) in charge of the
examples or maybe just this one add more to this though?

It may seem redundant to those that are comfortable configuring the
bricks, but myself, I dont fully understand what should go where, what
order. I understand this is a hard question to answer though because
of how configurable glusterfs can be.

So my request I guess is specific to a 2 machine, server side afr with
many clients config example(s).

Maybe start with the basic one that is there, then add a few more
examples with how you might tune it with performance translators and
such. It would just save a little time compared to the trial and error
method.
