       -z, --size=
              Amount  (in  Kibibytes)  of space to use from each drive in RAID
              level 1/4/5/6.  This must be a multiple of the chunk  size,  and
              must  leave about 128Kb of space at the end of the drive for the
              RAID superblock.  If this is not specified (as  it  normally  is
              not)  the smallest drive (or partition) sets the size, though if
              there is a variance among the drives of greater than 1%, a warn-
              ing is issued.

              This value can be set with --grow for RAID level 1/4/5/6. If the
              array was created with a size smaller than the currently  active
              drives,  the extra space can be accessed using --grow.  The size
              can be given as max which means to choose the largest size  that
              fits on all current drives.

       -c, --chunk=
              Specify chunk size in kibibytes.  The default is 64.
