I'd say that's more important than linear or raid0. ;-) Also, the next step in this work is to then decide how to determine on what numa node an LBA resides. We had discussed this at a prior plumbers conference, and I think the consensus was to use xattrs. Toshi, do you also plan to do that work? Cheers, Jeff
