Actually, you won't see any change at the lustre level, except bigger target support. Rebasing ldiskfs on ext4 allows us to reduce the number of patches we have to apply (e.g. extents, mballoc, ...) and to take advantage of fixes that went into the mainline and were not in our ldiskfs patches. > I'd assume that 1.6 ext3 based lustre fs cannot be upgraded to ext4 based? Yes, you can upgrade from ext3 to ext4. > How about quota support? No change.
