Bug#443897: cdrom: Freshly installed system with hardware RAID doesn't boot
Justification: breaks the whole system
I have a server with an onboard Adaptec RAID bus controller (ASR-2010s).
After the fresh installation of stable Debian 4.0 distribution my system
was rendered unbootable. It got stucked waiting for the root partition.
The main problem was that grub menu entries were pointing at /dev/sda1
as the root partition, while the Linux kernel didn't know that name.
Booting message issued by "block-osm" reported registration of i2o/hda
device, so the root partition was apparentely seen as /dev/i2o/hda1.
Manual editing grub entry has helped to mount the root partition, but
the system was unable to mount all the other partitions, because all
fstab entries created by the installer were also following the
"/dev/sda" schema. Renaming them to the "/dev/i2o/hda" schema fixed this
problem and my system started to work as expected.
But I faced the problem with grub once again few minutes later, after
the kernel was upgraded with standard "apt-get dist-upgrade" operation.
Soon I have discovered that it was most probably caused by "update-grub"
script. Every time it was activated, both entries in /boot/grub/menu.lst
file were pointing at root partition /dev/sda1 again. I had to change
# kopt=root=/dev/sda1 ro
to look like this:
# kopt=root=/dev/i2o/hda1 ro
This was the right solution. Now my update-grub script does not break
root partition name in grub entries anymore.
I'm not sure if this is a grub issue or maybe the installer's fault,
but I don't know how to check it, so I leave it at the CD level.
