31 * near_copies (stored in low byte of layout)
39 * in a style similar to raid0, but near_copies copies of each chunk is stored
41 * near_copies from the starting device of the previous section. Thus there
42 * are (near_copies * far_copies) of each chunk, and each is on a different
43 * drive. near_copies and far_copies must be at least one, and their product
52 * sets that are (near_copies * far_copies) in size. The far copied stripes
53 * are still shifted by 'near_copies' devices, but this shifting stays confined
565 * parameters: near_copies and far_copies.
566 * near_copies * far_copies must be <= raid_disks.
569 * If near_copies == raid_disks, we get raid1.
571 * Chunks are laid out in raid0 style with near_copies copies of the
572 * first chunk, followed by near_copies copies of the next chunk and
575 * as described above, we start again with a device offset of near_copies.
