[Bug 1077650] Re: booting from raid in degraded mode ends in endless loop

[Bernd Schubert]

I'm not so sure about that, without "bootdegraded=yes" it drops me to the shell and I only need to exit from that shell to continue to boot - the md-raid is already assembled then. 
I really don't see a reason why the boot script should assemble differently with or without "bootdegraded=yes". If at all, it only should check for failed devices if "bootdegraded=no". And I also really think the hole boot-to-shell should be given up at all in favour of a GUI pop-up.

Title:
  booting from raid in degraded mode ends in endless loop

Status in “initramfs-tools” package in Ubuntu:
  Confirmed

Bug description:
  Its basically the same as reported here:

  http://efreedom.com/Question/6-103895/Can-Boot-Degraded-Mdadm-Array

  So I just installed a new system, which is supposed to get later on an
  additional disk. For now I created md raid1 devices with one disk
  missing. To get ubuntu booting at all without complaining about a
  missing disk I already added "bootdegraded=yes" to the kernel command
  line. And now it ends in an endless loop of

  unused devices: <none>
  Attempting to start the RAID in degraded mode...
  mdadm: CREATE group disk not found
  Started the RAID in degraded mode.
