	As Brian said, the shared IP here for Apache is
independent of Gluster in this particular configuration.  I would
recommend something lightweight like UCARP so you can avoid
running any of the Linux cluster stack pieces:

	You're already attempting to avoid the cluster stuff
anyway and keep things simple by using Gluster.  No point in
adding all the HA bloat now just to balance an IP address.  And
UCARP can do that for you!  And don't forget to give a nod to the
OpenBSD developers who make such wonderful technology in the
first place.

	Now if only we could get PF into Linux!  :)
