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

[Andrew Nagel]

A potential solution to one of the two problems effecting the raid boot
has been posted on one of the discussion threads on the topic:
http://ubuntuforums.org/showpost.php?p=11388915&postcount=18  I rolled
back to 11.04 on the box with this issue and since it is a race type
condition getting it reproducible in a VM is a bit ore challenging.   I
may try setting up a test case to see if I create an array with a large
number of discs it might be reproducible in that.

This does nothing to effect the poison pill bug with rad5 but it should
at least make it so the problem only occurs when there is actually a
degraded array, or a random disk from an old array in the system and not
for perfectly healthy arrays.

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.
