Diskfilter writes error when installing GRUB on a raid

I'm setting up a server running Arch with two raided drives:
cat /proc/mdstat

md127 : active raid1 sda[0] sdb[1]
      976631488 blocks super 1.2 [2/2] [UU]
      bitmap"1/8 pages [4KB], 65536KB chunk

have the following partition table created with cgdisk:
gdisk /dev/md/a

Number  Start (sector) End (sector)   Size        Code    Name
1               2048         4095    1024.0 KiB   EF02    grub
2           20973568    981469183    458.0 GiB    8300    /media
3          981469184   1461716991    229.0 GiB    8300    /var
4         1461716992   1941964799    229.0 GiB    8300    /srv
5         1941964800   1942374399    200.0 MiB    8300    /boot
6         1942374400   1953262942    5.2 GiB      8300    swap
7               4096     20973567    10.0 GiB     8300    /

The command I'm running:

sh-4.3# grub-install --target=i386-pc --recheck --debug /dev/md/a
...
grub-install: error: diskfilter writes are not supported.

What should I do to fix this error?
