glusterfs drupal

Prehaps someone can help me or at least point me in the right direction. If one needed to scale up a couple apache servers but share the docroot using a synchonized (common source) it seems glusterfs is a good solution. I have set up an experimental Glusterfs replicated system (2 instances, each both master and client) with linux (ubuntu), apache and php on them. Got Glusterfs working fine, however I am a little unclear how to "link" /var/www to the glusterfs client mount point (e.g. /mnt/point). Not sure how to bring drupal and Glusterfs together using "best practices."
