In case you wanted to know:

1.
create and mount bricks

2.
install glusterfs
go here:
http://www.gluster.org/download/
follow the instructions. basically follow the instructions in the readme: http://download.gluster.org/pub/gluster/glusterfs/3.3/3.3.1/CentOS/readme.txt. Except instead of just doing
yum --enablerepo=glusterfs-epel install glusterfs
ALSO do these:
yum install glusterfs-fuse
yum install glusterfs-server

3.
make sure to open ports and/or disable SELinux/firewalls, etc

4.
Also make sure that glusterd and glusterfsd are running

5.
Run peer probe from the primary glusterfs server. DO NOT run it from the other gluster servers.

6.
Create the gluster volume on the primary server. For example:
gluster volume create thing1 underling1:/export/brick3 underling1:/export/brick4 underling2:/export/brick5 underling2:/export/brick6

7.
make sure glusterfs and gluster-fuse are installed on the client
