If you are using CentOS 3.5 then you want the el3 version of GFS from here:

This is only GFS 6.0 but it works well.  It looks like there are lots of 
differences in 6.1 so I don't think it will work out of the box on CentOS-3.

I use GFS with GNBD and it works OK.  Some of the nodes are 2 hops away 
over the ethernet and they can sometimes be a bit slow.  They also lock 
up if the network goes down (no hardware fencing).

The servers are in the same rack and work well together.

I don't know the maximum filesystem size, or if your hardware is 
supported but read the docs and it won't cost you anything to try it.
