[Bug 1202955] Re: (fakeraid) root device not activated during boot

[Phillip Susi]

By the way, if you are not dual booting with Windows, you should avoid
using the fakeraid and stick to traditional mdadm software raid, which
is much better supported and more feature complete.

Title:
  (fakeraid) root device not activated during boot

Status in “dmraid” package in Ubuntu:
  New

Bug description:
  I've just installed a HP Microserver (N40L) with the latest installer
  from precise-updates/main/installer-amd64/20101020ubuntu136.9/images
  /quantal-netboot. The installer fails to activate the raid, so I had
  to drop into a shell, write dmraid -ay, to continue the installation.

  After the install, I have the exact same problem, I'm always dropped
  into the busybox initramfs shell, write "dmraid -ay" to activate the
  raid, and "exit", and boot continues as normal.

  I've solved my problem by adding the line "[ -x /sbin/dmraid ] &&
  /sbin/dmraid -ay" to the end of the /usr/share/initramfs-tools/scripts
  /local-top/dmraid as suggested in
  https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/247027/comments/21

  But I'm guessing there's a more sophisticated procedure that's not
  kicking in on my system. What information can I start providing to
  help get this fixed? (If there's a ubuntu developer interested, I can
  provide access directly to the box via the ilo device.)

  (initramfs) blkid
  (initramfs) blkid -p /dev/sd[a-d]
  /dev/sda: TYPE="promise_fasttrack_raid_member" USAGE="raid"
  /dev/sdb: TYPE="promise_fasttrack_raid_member" USAGE="raid"
  /dev/sdc: TYPE="promise_fasttrack_raid_member" USAGE="raid"
  /dev/sdd: TYPE="promise_fasttrack_raid_member" USAGE="raid"

  Without any parameters blkid doesn't return anything.

  (initramfs) dmraid -ay
  RAID set "pdc_ebdeeaiceb-0" was activated
  RAID set "pdc_ebdeeaiceb-1" was activated
  RAID set "pdc_ebdeeaiceb" was activated
  RAID set "pdc_ebdeeaiceb1" was activated
  RAID set "pdc_ebdeeaiceb2" was activated
  RAID set "pdc_ebdeeaiceb3" was activated

  I'm filing it under linux-lts-quantal, since it's the highest level
  package (I think) that is affected by the underlying problem. And I'm
  told it's not related to
  https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/941874

  linux-image-3.5.0-36-generic #57 precise1 (amd64)
  dmraid 1.0.0.rc16-4.1ubuntu8
