If so, what is the > maximum block size supported in GFS The difference in quoted max size limits (1 or 2 TB on 2.4 and 8 or 16 TB on 2.6) shows up because some people trust block/page numbers that use the sign bit and some don't. It may very well be possible to go to larger sizes on your hardware and drivers, but you need to check to verify that yourself. I'm paranoid and will quote you the smaller number. :-) -- Ken Preslan <kpreslan@xxxxxxxxxx>
