Bug Description

instlaler installed everything to a fairly sane raid setup (/boot on hda1, / on md0) but on reboot the kernel couldn't mount md0 on /

Feb 24 13:26:56 dhcp179 kernel: [4294667.296000] Kernel command line: root=/dev/md0 ro quiet splash

[81390.392867] VFS: Can't find ext3 filesystem on dev md0.

dropped me to a prompt where I was able to --stop the raid and mount -t ext2 -o ro /dev/sda2 /root/ - exit and the box booted.

Here is a copy of /etc/ and /var/log : http://dev.personnelware.com/carl/temp/Feb24/ubuntu-installs/a/
 I'll attach a dmesg, syslog and a few others.

strange: a similar setup on a 2nd box works better: it boots, but has disturbing messages:

fdisk -l = Disk /dev/md0 doesn't contain a valid partition table

[4294691.920000] md: md0: raid array is not clean -- starting background reconstruction

Few things that are different: 2xPIII, scsi, slightly different partition layout (but /boot and / are about the same)

scp -r /etc /var/log fdisk.txt to http://dev.personnelware.com/carl/temp/Feb24/ubuntu-installs/b/

I hear this is normal:

fdisk -l = Disk /dev/md0 doesn't contain a valid partition table

also, both setups are from the same ubuntu-server build, both using the same preseed file for everything except the partitioning

This only means that md0 hasn't an ext3 partition (it could be
reiserfs or any other).

Can you provide us with an update about this issue?
Did you try with newer Dapper or Edgy?
Is this bug related to bug #31435, as Simon pointed?

Thanks!
