Thanks for the explanation. > sector_size is the drive's logical sector size. This must be a multiple of phys_sector_size, right? > Both of them have nothing to do with the file system's block size; Yes, I see that's true when we're talking about a real device, but... > the three constraints are imposed separately on alignment calculations. ...when using a regular file (init_file), sector_size is set to PED_SECTOR_SIZE_DEFAULT unconditionally, regardless of the underlying file system block size. But here, it matters for O_DIRECT on losing (e.g. 2.4.x) systems. _______________________________________________ parted-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/parted-devel
