Package: debian-installer
Version: 4.0r3
Severity: critical
Justification: breaks the whole system
I installed a debian stable system on a Pentium 4 machine with 4 320GB ide disks and the installation goes well,
but when it comes to installing grub on the MBR i get an error and i cannot continue.
The raid array is set up like this:
root@amaro:/# mdadm --query --detail /dev/md0
/dev/md0:
Version : 00.90.03
Creation Time : Thu Mar 13 16:58:31 2008
Raid Level : raid5
Array Size : 624028544 (595.12 GiB 639.01 GB)
Device Size : 312014272 (297.56 GiB 319.50 GB)
Raid Devices : 3
Total Devices : 4
Preferred Minor : 0
Persistence : Superblock is persistent
Update Time : Thu Mar 13 22:00:25 2008
State : active
Active Devices : 3
Working Devices : 4
Failed Devices : 0
Spare Devices : 1
Layout : left-symmetric
Chunk Size : 64K
UUID : 55663848:a9ede020:1073524f:ba97c07f
Events : 0.3
Number Major Minor RaidDevice State
0 3 65 0 active sync /dev/hdb1
1 22 65 1 active sync /dev/hdd1
2 33 65 2 active sync /dev/hdf1
3 34 65 - spare /dev/hdh1
I chrooted in the target directory from the debian installer but i could not get grub to install by hand as this is the output:
root@amaro:/# grub-install /dev/hd[b|d|f|h]
Searching for GRUB installation directory ... found: /boot/grub
The file /boot/grub/stage1 not read correctly.
(the [] means i tried all the devices but none worked).
The stage1 file exists:
root@amaro:/# file /boot/grub/stage1
/boot/grub/stage1: x86 boot sector, code offset 0x48
root@amaro:/#
and the device.map file is as follows:
root@amaro:/# cat /boot/grub/device.map
(hd0) /dev/hdb
(hd1) /dev/hdd
(hd2) /dev/hdf
(hd3) /dev/hdh
root@amaro:/#
I saved all the logs the debian installer gave me, they can be found at

Grub does not support RAID5, only RAID1 and RAID0. So you've asked it to do
something impossible. Lilo does not support RAID5 either.
The correct solution is to create a separate /boot partition.
As this is not an installer bug but user error (when you do manual
partitioning and use advanced options like RAID5 you're somewhat expected
to know their limitations), I'm closing your report.
Cheers,
