[Bug 1274320] Re: Error: diskfilter writes are not supported

[fermulator]

I just tried applying the patch manually and re-ran grub-install, not go.
I also tried pulling in the patch via Forest (foresto) PPA: https://launchpad.net/~foresto/+archive/ubuntu/ubuntutweaks, also no go.


fermulator at fermmy-basement:/$ sudo grub-install /dev/md0

grub-install: error: diskfilter writes are not supported.

Title:
  Error: diskfilter writes are not supported

Status in GRand Unified Bootloader:
  Unknown
Status in grub2 package in Ubuntu:
  Confirmed
Status in mdadm package in Ubuntu:
  Invalid

Bug description:
  Once grub chooses what to boot to, an error shows up and will sit on
  the screen for approx. 5 seconds

  "Error: diskfilter writes are not supported.
  Press any key to continue..."

  From what I understand, this error is related to raid partitions, and
  I have two of them (md0, md1). Both partitions are used (root and
  swap). Raid is assembled with mdadm and are raid0

  This error message started appearing right after grub2 was updated on
  01/27/2014.
