Status in “mdadm” package in Ubuntu:
  New

Bug description:
  mdadm --grow --chunk=256 /dev/md1
  mdadm:option --chunk not valid in grow mode

  root at talli:~# mdadm -V
  mdadm - v2.6.7.1 - 15th October 2008

  man mdadm:
  For create, build, or grow:
  ...
         -c, --chunk=
                Specify chunk size of kibibytes.  The default is 64.

  Thus should be supported but is not
