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.

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. > > It looks like no matter what I do, I need a second box next to the > first one to redirect packets to the other box if one of the boxes > goes down.

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