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

[DooMMasteR]

passing 'bootdegraded=true' is no solution

so far I have found no way to boot my system.
As long as a disk which is part of an incomplete RAID is connected I will always end up in a BusyBox recovery shell, one way or another.

this is really annoying and can by far not be an intended feature…
it also does not matter if the RAID is included in mdadm.conf or if it is completely empty

I would understand this way of problem handling if the RAID contained
essential data and was needed, but it will never be mounted during
bootup and also is not contained in fstab, it is as if a broken device
just prevents your system from bootup (in fact any USBthumbdrive with a
Superblock describing it as part of a large RAID will do that)

I can obviously just disconnect my disks but that is not the case if the
machine is unattended and had to reboot for one reason or another, when
the RAID is not synced it will just fail to boot (there would not even
be sshd running to offer remote access)

we had that situation before and I could then force assemble the RAID
remotely but only because 10.04 would boot even with an degraded RAID
attached

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.
