Hi Riaan,

Sorry about the document; this isn't any secret information.  What GFS 
does and how it works is all out there,
in the public domain, but I don't want to mislead people with old 
information.
As I said, I am planning on writing a white paper with details about the 
inner workings of GFS, and I'd
be happy to get your feedback as I did with the NFS/GFS cookbook.
I'll go over Ken's email to make sure I cover everything that's in there. 

As far as the NFS issues are concerned, they are all documented in 
bugzilla(s) such as the one
I mentioned in my other email, which is 178057.

As far as Tom Mornini's inquiry...Tom Mornini wrote:

He said he is "about to setup a cluster" with NFS/GFS, which I take to 
mean that
he's looking for setup information, not for obsolete technical notes 
about the design of GFS2.
