Bug#607565: initramfs-tools: initramfs fails to assemble Intel RAID array

Package: initramfs-tools
Version: 0.98.6
Severity: grave
Tags: patch
Justification: renders package unusable

I just installed Debian (Sid) on my PC and was in for a nasty surprise; the
system wouldn't boot after install.

I have 2 disks setup in an ICH9R raid set, which devides these 2 disks in 2
arrays; 1 is a RAID0 array, and 1 is a RAID1 array. This is a completely valid
configuration for an Intel RAID set.

I installed Debian on a LVM setup, using a partition in the RAID0 set as a PV.
The /boot partition is also an LV.

As I found out, the Intel RAID system works with a "container", which contains
the arrays. The container was assembled during boot, but the arrays fail to
assemble, giving a "device or resource busy". The problem is almost exactly the
same as seen in this URL: http://www.linux-archive.org/debian...54103-how-
recreate-dmraid-raid-array-mdadm.html

I did, however find a different workaround. Removing the /etc/mdadm/mdadm.conf
and running mdadm -Ss && mdadm -As also assembles the arrays correctly.

For people stumbling into the same problem; here are steps to work around this
problem:
- Wait for the ramdisk to put you in a (initramfs) shell.
- mdadm -Ss
- rm /etc/mdadm/mdadm.conf
- mdadm -As
- lvm vgscan
- vgchange -ay

Now, mount the boot partition to a directory, e.g. /root
- mount /dev/vgMain/lvBoot /root
- mkdir /root/temp
- cd /root/temp
- gunzip ../<initrd image> | cpio -i
- rm etc/mdadm/mdadm.conf
- find . | cpio -H newc -o > ../initrd.new
- cd ..
- gzip -9 initrd.new
- cd
- umount /root
- reboot

And use the "edit" option in grub to select /initrd.new.gz as your new initrd
image.

Some information on my particulair configuration:
