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

[Adam Conrad]

Hello Eike, or anyone else affected,

Accepted mdadm into precise-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/mdadm/3.2.5-1ubuntu0.2
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Changed in: mdadm (Ubuntu Precise)
       Status: In Progress => Fix Committed

** Tags added: verification-needed

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

Status in “mdadm” source package in Precise:
  Fix Committed
Status in “mdadm” source package in Quantal:

Bug description:
  [Impact]
  This is an SRU regression confined to precise-proposed.  Reverting part of the upstream changes is sufficient to resolve this for precise.  The issue remains unfixed in quantal; this is not a blocker for the SRU.

  [Test case]
  Verify that the submitter's machine boots successfully with the latest mdadm installed.

  [Regression potential]
  Since the existing mdadm in precise does not do auto-assembly of imsm or ddf arrays using udev rules, the risk of regression by continuing to not assemble them is minimal.  Only risk of regression is a mis-edit causing some other array, previously handled correctly in precise, to no longer be assembled; the risk of this is very small.

  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.
