[Bug 872220] Re: Fails to boot when there's problems with softraid

[Marcus Overhagen]

I just made a full update on a 180 days old 12.04.2 system. Everything
was fine before, but on reboot I'm dropped into this rescue shell,
because /dev/sdc1 is detected as belonging  to a degraded raid.

However, the raid is not degraded! cat /proc/mdstat shows it as healty
(keyboard is working), and after I type exit boot continues normally.

cat /proc/mdstat

Title:
  Fails to boot when there's problems with softraid

Status in “mdadm” package in Ubuntu:
  Triaged

Bug description:
  Ubuntu 11.10 has a new feature that it warns you while booting if
  there's a program with the softraid.

  It tells you that a hard disk in the softraid is missing, then asks,
  on the console:

  Continue to boot? y/N

  But it ignores all keypresses. After 5 seconds or so it then times
  out, falls to the default "N" option, and dumps you to a emergency
  bash prompt, with no indication on how to proceed.

  The feature is a good idea, but not in the current broken state.
