Is Redhat GFS opensource?

["Brent M. Clements" <bclem rice edu>]

Good Morning All,

I'm a bit confused.

I go to the Redhat GFS webpage and it has a link to purchase redhat GFS
for $2,200. But..the very first line of the description says this. "Red
Hat Global File System (GFS) is an open source, POSIX-compliant cluster
file system and volume manager that executes on Red Hat Enterprise Linux
servers attached to a storage area network (SAN)."

So which is it? Is it a commercial closed source product which I must buy,
or can I freely download the sources and modify? I can't seem to find
Redhat's GFS sources anywhere.

I know about OpenGFS but that is not the same product that Sistina
sold to Redhat from what I understand.
