During the recent IO/FS workshop, we spoke briefly about the coming change to a 4k sector size for disks on linux. If I recall correctly, the general feeling was that the impact was not significant since we already do most file system IO in 4k page sizes and should be fine as long as we partition drives correctly and avoid non-4k aligned partitions.Sorry about jumping right in, but what about an 'old-style' partition table that relies on 512 as a unit?
I think that the normal case would involve new drives which would need to be partitioned in 4k aligned partitions. Shouldn't that work regardless of the unit used in the partition table? ric
