Yes, that if for the shared gfs between the node. What we've decided to use 
is 2 raid-1 sets of 1 tb (2 disk each), added to a single vg of 2 tb. Other 
raid sets will be mounted on a per-node and per service basis.

I know I can make a gfs on a standard partion, but to make a larger than the 
disk volume, I need either raid or lvm. Lvm adds also the ability to add 
space later.

I am currently using RHEL6 beta, while waiting for centos 6 to be out in a 
couple of weeks. I dont' think gfs1 is included with rhel6.
