from mdadm man page, it seem raid1 don;t spport chunk.

 -c, --chunk=
              Specify  chunk  size of kilobytes.  The default when creating an array is 512KB.  To ensure compatibility with earlier
              versions, the default when building an array with no persistent metadata is 64KB.  This is only meaningful for  RAID0,
              RAID4, RAID5, RAID6, and RAID10.

              RAID4, RAID5, RAID6, and RAID10 require the chunk size to be a power of 2.  In any case it must be a multiple of 4KB.

              A suffix of 'K', 'M', 'G' or 'T' can be given to indicate Kilobytes, Megabytes, Gigabytes or Terabytes respectively.
