(1) The iptables examples at http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/IG/html/chap -Installation_Guide-Installing.html#sect-Installation_Guide-Installing-RPM and at http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/IG/html/sect -Installation_Guide-Installing-Source.html contradict each other. Both are supposed to be for "20 storage servers and 3 bricks". However the first opens ports 24007:24047 and 38465:38467 (i.e. 41 ports and 3 ports), and the second opens ports 24007:24011 and 38465:38485 (i.e. 5 ports and 21 ports) (2) I imagine this means 3 bricks *per server*, in which case I think it would be clearer to say "20 storage servers each with 3 bricks" or "20 storage servers and 3 bricks per server" (3) The first URL says "(24009 + number of bricks across all volumes)" which I think is incorrect; it suggests to me that you would have to open 60 ports on a single server in this example.
