OK, great.  So basically just install the gluster server on the new
node(s), do a peer probe to add them to the cluster, and then

gluster volume create palantir replica 3 arbiter 1 [saruman brick] [gandalf brick] [arbiter 1] [azathoth brick] [yog-sothoth brick] [arbiter 2] [cthulhu brick] [mordiggian brick] [arbiter 3]

Or is there more to it than that?
