I track the OpenGFS development list and it is clear that it has a ways to
go with respect to robustness of lock management. I don't think that 
porting would be that major an undertaking. However, It almost seems that
adding clustering to an existing journalled file system would be easier
than stabilizing OpenGFS. Lustre is designed for extremely large local

This is not at all what OpenGFS is designed for. That is something that
AFS would be perfect for. However, Transarc botched it with respect to
the market. At least in the medium term NFSv4 is probably the closest
you're going to get.

I'm sure some of the ASPs must have solved that problem.
