32 * far_copies (stored in second byte of layout)
38 * is divided into far_copies sections. In each section, chunks are laid out
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
46 * If far_offset is true, then the far_copies are handled a bit differently.
52 * sets that are (near_copies * far_copies) in size. The far copied stripes
