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

[Dimitri John Ledkov]

Brian Morton (rokclimb15) & Thiago Martins (martinx) please open new
bugs about your issues.

We have automatic testing of RAID installations and degraded-boot
testing. However I do not believe we test "actually performing the
installation degraded". I will check our test scenarios and test the
conditions described above, when i get time later this week.

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

Status in “mdadm” 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.
