[Bug 1030292] Re: initramfs does not boot with mdadm (3.2.5-1ubuntu0.1)

[Steve Langasek]

here's the exact bit from mdadm.conf:

# definitions of existing MD arrays
ARRAY metadata=imsm UUID=e44d6ca8:d2446b48:d6cdedd2:153ecfc5
ARRAY /dev/md/Volume0 container=e44d6ca8:d2446b48:d6cdedd2:153ecfc5 member=0 UUID=8fdb592d:c433e357:c4c0232b:71639fce

But this array does NOT appear in the udev.log.

Title:
  initramfs does not boot with mdadm (3.2.5-1ubuntu0.1)

Status in “mdadm” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to the mdadm in precise-proposed, all newly created
  initrds do not boot. I'm using a pseudo raid with to harddisks on a
  Sony Vaio Z. Raid level is 0.  I have one  unencrypted boot partition
  and an encrypted root.

  During startup the system asks for the password to decrypt the root
  partition as usual but fails to mount the partition afterwards. I
  always get the message that there are one or more degraded partitions.
  However, with an older version of mdadm everything works perfectly.

  My current solution: Downgrade to latest stable mdadm (precise).

  Please let me know what additional information is required. I can also perform some tests as long as my (prodcutive) system is not in danger.
