Before you proceed make sure you have physical volume(something like /dev/sda1, /dev/sda4, etc) with no data. This is going to be the gfs volume which you will export to other nodes. It should be on the node which is going to be your gnbd server. If you dont have such volume create one using fdisk.

I used mounted gfs volume as a DOCUMENT ROOT for my Apache server nodes(Load Balanced).

I tried it on FC4 64-bit. If you plan to try it on any other distribution or 32-bit arch.. still the procedure remains same. Since I built it from source but not RPMs, you may have to simply supply config options with a different CFLAGS.
