If you are using CentOS 3.5 then you want the el3 version of GFS from here: http://mirror.centos.org/centos-3/3/csgfs/
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.
From another thread:
"From what I've been reading, there's an 8TB limit of all GFS file systems in a cluster.

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup?
Is GFS stable enough to use in a production environment?
There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has
anyone
used this? Is it stable?
Will I run into any problems if I use CentOS 3.5 with it's GFS package
to
access a shared 5TB filesystem?
I've been googling on this stuff off and on for a month now. I've found
a
bunch of conflicting and confusing information, but no clear answers.
I've
been kind of hoping that the new GFS 6.1 packages would be released
while I
was waiting... :)
I appreciate any suggestions or pointers.
