I wish someone comfortable with GNDB and LVM Cluster Mirroring would 
write a howto/walkthrough to do this. I am going to try my luck 
submitting this question to kbase.redhat.com : How do I use GNDB + LVM 
Cluster Mirroring to simulate shared storage without a physically shared 
storage array? I know they will take their time if they even decide to 
answer it, so is anyone willing to try writing one?

It would be great if this could move past the ingredients phase ("use A, 
B and C") to the recipe phase ("first you ..."). There is definitely a 
huge demand for "pseudo-shared storage" clustering, based on what I have 
heard from my customers and what I have seen on this list.

(If I knew that opening a Service Request for that howto I might be 
compelled to do it.)
