I see.  Thank you for clearing that I'm.

I'm now guessing that the person who told me this was restricting his
vision to 32 bit hardware.

Would would GFS on kernel 2.6 do with a bunch of 32 bit machines with
disks attached to them, but a 64 bit client?

Is GFS for kernel 2.6 ready at this point?  Or nearly so?

Thanks for the great info.  :)
