[Bug 489826] Re: Upgrade to Karmic: can't boot, can't mount. Partitions missing from /dev/.

Sun Nov 29 20:28:54 UTC 2009

** Package changed: devicekit-disks (Ubuntu) => dmraid (Ubuntu)

** Description changed:

  Binary package hint: devicekit-disks

  After upgrade to Karmic, my machine will no longer boot with a "ALERT!
  /dev/disk/by-uuid/XXX does not exist." error.

  I did search the forums but my situation seems different from all of the
  problems I found in that:

-    1. Partitions (sda2 etc.) are missing from /dev/. There is an sda and sdb in /dev, but no partitions.
-    2. /dev/disk/by-uuid is missing completely. In /dev/disk there is only by-id and by-path.
+ [LIST=1]
+ [*]/dev/hda1 is also missing
+ [*]/dev/disk/by-uuid is [B]completely[/B] missing
+ [/LIST]

- Because of #1, the root partition is not mounted, and my machine is not
- bootable, so I had to file a ticket using this procedure:

- I've attached some boot debugging output from the bootinfoscript, but it hasn't shown anything useful so far.
- http://sourceforge.net/projects/bootinfoscript/

  I attempted to resolve my issues on the Ubuntu forums, but my problem doesn't seem to be a conventional one.
  The thread is here:
  http://ubuntuforums.org/showthread.php?t=1339024

- I've enabled udev debugging output, but can't think of a way to post the
- results while my disks are unmountable...
+ 
+ ------
+ Problem:
+ 
+ A long time ago I had my disks in a RAID array. The new dmraid package
+ in Karmic detected this and set up my disks to mount as raid. Note the
+ '/dev/sr0' partition shown above. Not very helpful...
+ 
+ ------
+ Solution:
+ 
+ Download and boot to a Karmic Live-CD.
+ Run the following to remove lingering RAID meta-data:
+ 
+ [CODE]sudo dmraid -E -r /dev/sda
+ sudo dmraid -E -r /dev/sdb[/CODE]
+
