[Bug 1309639] Re: Installer locks after failing to install GRUB onto RAID array

[Phillip Susi]

It looks like the problem is that your arrays are named rather than
numbered, so they are detected as md/root, and so on, but /proc/mounts
shows them being mounted by their numerical name ( /dev/md0 ).  It seems
that grub needs to sort out the fact that they can be referred to by
either name.


** Package changed: grub-installer (Ubuntu) => grub2 (Ubuntu)

** Changed in: grub2 (Ubuntu)
       Status: Incomplete => New

** Summary changed:

- Installer locks after failing to install GRUB onto RAID array
+ grub confused by named md raid arrays

Title:
  grub confused by named md raid arrays

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Am installing Trusty (AMD-64 Desktop), with /boot as a RAID-1 set
  (ext2fs) under mdadm on a GPT partition, with a separate, non-RAID,
  unformatted partition for BIOS-grub. At the stage of attempting to
  install GRUB it fails, reporting fatal error. I get the window
  offering the option (among others) to continue without installing GRUB
  anywhere. I select this option, but the "OK" button never becomes
  active and no further progress occurs. The installer shows signs of
  having "crashed" or "locked-up", so I cannot be confident that the
  remainder of the installation has been completed, otherwise I could
  assemble the RAID-sets at a mount-point, then chroot and complete the
  installation of GRUB that way. I know that this build isn't intended
  for RAID installations, but a clean failure would be helpful. Thank
  you.
