[Bug 1078407] Re: pdc fakeraid not recognized

[Guido van Loon]

My system has two 120GB disks. Both are used in a RAID0 configuration with the fakeraid controller.
ls /dev/sd* gives me sda, sda1, sdb and sdb1.

sudo fdisk -lu /dev/sda does not give any results, no output at all
sudo fdisk -lu /dev/sda1 you can see in comment 18
sudo fdisk -lu /dev/sdb you can see in comment 19
sudo fdisk -lu /dev/sdb1 does not give any results, no output at all

i've attached the output of sudo dd bs=512 skip=234374049 count=1
if=/dev/sda | hd in a file called dd_dev_sda

I want to thank you for your patience and not giving up on me already.
Thanks!

Title:
  pdc fakeraid not recognized

Status in “util-linux” package in Ubuntu:
  In Progress

Bug description:
  I have a fresh install of Ubuntu Desktop on my old Dell Dimension
  8300. This box has a Promise Fasttrak raid controller a.k.a. softraid
  or fakeraid.  It is setup with two identical drives in raid0, stiped.

  I had a hard time getting the installer to run without errors. Did all kind of manual steps to make the installer complete.
  I installed from a pendrive, booted the liveCD. Used dmraid -ay and gparted to partition the drive. Did nothing special with the partitions one swap and one root partition. The installer ends up grubbing my pendrive instead of my harddisk so I followed a manual to purge an reinstall grub2 on the correct disk here (http://ubuntuforums.org/showthread.php?t=1581099)

  Now when I boot, the computer shows a graphical off-black screen
  (ubuntu boot color???) and nothing happens. When I then reboot with
  Ctrl+Alt+Delete a second time. I get GNU GRUB menu and I choose
  "Ubuntu, with Linux 3.2.0-29-generic-pae". After a while I got thrown
  in busybox because of the root device was not found: ALERT! /dev/disk
  /by-uuid/8693f1c2-3eb1-41a4-ba10-3fbe860144a1 does not exist.

  When I type "dmraid -ay" [Enter]
  I see three messages like RAID set "pdc_ccgcdegci" was activated. 
  Press Crtl+D the computer will continue to boot normally.

  The next time I boot I need to reboot to get pass the off-black screen
  and into the GNU Grub menu again.

  I found bug report 941874, but I checked and the fixes described there seem to be in place on my machine...
  I tried the steps described in "http://www.humans-enabled.com/2012/03/how-to-fix-ubuntu-1204beta-boot-problem.html" to no avail.

  I'm new to the whole Ubuntu/linux thing and I just want my computer to
  boot without manual intervention. Please help.

  Thanx!
