Yes, I was aware of this as well.  I just blanked on it in
my first email.

Sorry, of course Lustre should have been on this list.
Does GFS work in distributed mode?  I didn't add it
to the list because since it is a shared filesystem
(multiple clients access the block devices directly)
I didn't include it.  If we include GFS, then we
also have to include at least SGI CXFS and ADIC StorNext.
