I just assume you're planning to do this on Linux.
Since there is no other fileserver than a 'namei' on Linux, you can
use it on any device (the LVM is usually completely transparent) and
with any filesystem you think it suits best.
For the rest of the questions, I don't know how you think you can
If you want to use available storage from all of your fileservers,
that's what AFS will help you do.
You'll have one namespace and from a users perspective you won't have
to care about where the storage actually is located.
Actually that's what a distributed and even a network file system is
If you think of placing the network some layers lower, like in the
block device, etc., AFS can't help.
