[Bug 931929] Re: root on RAID:0 fails to boot

[GLehnhoff]

I got this problem suddenly today with 14.04 on SDD/brtfs, shortly after
I switched to NVIDIA driver, as the standard one crashes (known bug). As
my disk is not an array, dmraid -ay does not help (command does not
exist). Disk mounts perfectly in another Ubuntu. Current Ubuntu does not
start anymore.

  root on RAID:0 fails to boot

Bug description:
  Booting from RAID is often broken after upgrades or fresh
  installations of Ubuntu.

  initramfs is not activating RAID devices.

  Steps to reproduce:
  1. Upgrade or Install Ubuntu on a RAID
  2. Reboot
  3. Observe failure to find root drive and drop to busybox

  To work around this, when given the busybox prompt enter:

  dmraid -ay

  Verify that all of your raid devices are initialized, then enter:

  exit

  Booting should then continue.

  See comment #2 for a persistent (rebootable) workaround.
