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

[Eike Thaden]

Unfortunately I have not idea how to find out wether dmraid or mdadm is
used (or even both). Btw. as far as I can see the system is using lvm on
top of the raid with an unencrypted boot partition and encrypted root
and swap partitions. This was not my idea but was proposed by the ubuntu
installer.

I attached the output of dmesg and hope this helps to solve that riddle.

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.
