[Bug 1004376] Re: Grub2 with RAID+LVM no longer fits in 62 sectors

[zeukiller]

Hi,
And thanx for the answer.
So if I understand correctly what you said, I must increase the size of my boot sector from 62 to 2048 ?
Is it possible ? and how ? ... it sounds a little bit risky, no ?

Title:
  Grub2 with RAID+LVM no longer fits in 62 sectors

Bug description:
  Hi,
  During installation of Ubuntu 12.04, I can not finish the installation correctly, because the installation of grub goes wrong.
  Indeed, during the installation of grub I have a recurring error as follows:
  /usr/sbin/grub-setup: warn: Your embedding area is unusually small.  core.img 
  won't fit in it..
  /usr/sbin/grub-setup: error: embedding is not possible, but this is required 
  when the root device is on a RAID array or LVM volume.

  I'm running on 64bits plateforme, with LVM over RAID partitions. The same installation works perfectly with Ubuntu 10.04.3 LTS.
  Here are more informations about my partitions : http://paste.ubuntu.com/1003855/
