[Bug 1004376] Re: Grub2 install failed in Ubuntu 12.04 install on RAID/LVM partitions

[Phillip Susi]

It appears that the size of the grub2 core image when raid and lvm
modules are included has increased slightly since 10.04, and no longer
can fit in 62 sectors.  It is now the norm for partitions to be aligned
to a 1 MiB boundary, leaving 2047 sectors for the embed area, but your
partitions start on sector 63 instead.


** Changed in: grub2 (Ubuntu)
       Status: Confirmed => Triaged

** Summary changed:

- Grub2 install failed in Ubuntu 12.04 install on RAID/LVM partitions
+ 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/
