Given the content of patch ea9df4...it might be of interest that my dasd devices have a hard sector size of 4k: $ sudo blockdev --getss /dev/dasdf1 4096 $ sudo blockdev --getbsz /dev/dasdf1 4096 Since I always get confused by the internal 512 bytes vs. hard sector size vs. block size vs. file system block size I dont know if that is important.
