Does it help that you can add your own scripting or binaries to
/usr/lib64/glusterfs/3git/filter/ to create/modify/delete options
in generated .vol files automatically? (you might need to create that
directory first)

With a script, you could definitely read in values from an external source
such as a filesystem location, remote database, etc, then apply them.

It's not a great way to do things, but it works.
