I was just looking at the OES2 beta documentation which looks to have been
recently updated:

It appears the max volume size is still going to be 8-terabytes with OES2
Linux :-( I'm almost certain that one of the Brainshare 2007 presentations
said this limit was going to be raised., but I can't find those
presentations online anywhere.

If anyone has any official info to the contrary, please reply here.
