Thank you, and sorry for the late response.

After the latest aptitude dist-upgrade, I too got hit with bug #56782,
which caused me to investigate the entire boot sequence again.

After a couple of changes, update-grub2 and friends do not tell me no
such file or directory, but just work as expected without error.

This also seems to be causing the RAID array to be assembled correctly
on boot (though I think it too got updated during the process).
Without the DEVICES line in the mdadm.conf and with a correct and
working devices.map, everything works.

Thanks for your help.

Hmm, in contrast to my previous remark, this does NOT resolve the issue
it seems.

I can now succesfully start the array from the initrd prompt using mdadm
-As, but the /scripts/local-top/mdadm script cannot.

It complains cannot find /proc/mdstat. If I modprobe the md module from
the prompt, and then manually run /scripts/local-top/mdadm, it does
assemble the array.

I'm just not really sure where to tell local-top to load this module...

Not sure if it is important or not, but update-iniramfs -u gives me an

 Do you still have that mdadm.conf and could you please provide it

Ofcourse.

The /etc/mdadm/mdadm.conf orginally looks like this:

DEVICE partitions
HOMEHOST system
ARRAY metadata=imsm UUID=5a17be47:4c36e982:9fd7aa92:6b23c688
ARRAY /dev/md/BootEnBackup container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=0 UUID=9e35:67d59d42:043dbdde:fe757582

member=1 UUID=8a981b80:aa2c2f06:e4ec50a5:9045f323

Looks pretty much OK though... A mdadm -Es gives me the same numbers:

ARRAY metadata=imsm UUID=5a17be47:4c36e982:9fd7aa92:6b23c688
ARRAY /dev/md/BootEnBackup container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=0 UUID=9e35:67d59d42:043dbdde:fe757582
ARRAY /dev/md/Data container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=1 UUID=8a981b80:aa2c2f06:e4ec50a5:9045f323

I think the DEVICE actually has to be containers. Also, I'm not sure
if the gethostname() call implied by system will work in initrd.

I'll do some tests and see what works.

Sincerely,
Roel

OK. It's definably the DEVICE line which is stopping the arrays from
being assembled and started.

I changed DEVICE to containers, but it told me None of the devices in
the configuration file could be found.

Simply changing the DEVICE line to something wrong like foo, causes
mdadm to give a warning (Invalid DEVICE line), but it assemble the
arrays correctly.

Removing the line has the same effect.

Changing only the HOMEHOST line does nothing. Setting it to localhost or
the hostname of the machine with the DEVICE partitions still in place,
does not help.

However, using the default configuration does give me a Container imsm
assembled. The arrays themselves are not started.

Sincerely,
Roel

This is the correct fix.  Remove the DEVICE line.

The default DEVICE line (which is in effect if no DEVICE line is explicitly
given) is

   DEVICE partitions containers

which essentially means feel free to use use anything in an md array.

A DEVICE line is only needed if you want to explicitly list some smaller
subset of things.

There was a time when a DEVICE line was needed, but that is long gone now.

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

2011-01-25 Thread Alexander Hofbauer
Hi!

I think I was facing the same problem the other day and I hope this is
related.

The array holding the root partition wouldn't be assembled and stay
read-only due to the fact that mdadm couldn't start mdmon, which was not
included in the ramdisk.

Writing a quick'n'dirty hook for initramfs-tools adding mdmon
auto-magically fixed that.

--8---
/etc/initramfs-tools/hooks/mdmon:

#!/bin/sh

. /usr/share/initramfs-tools/hook-functions
copy_exec /sbin/mdmon
--8---


I can't shutdown the system in a clean way though, it stops at some
point (magic SysRq keys still work). I guess it's trying to unmount the
root after mdmon has been killed with all the other processes?



Best regards,
Alex

No, it is mounted auto-read-only as long as there are no writes to
the device. This is a security measure. I see no reason why mdmon
should help with this.

Ext4 was complaining about a read-only device, initramfs did't continue
booting and I couldn't enable write access (neither via mdadm
--readwrite or /sys/class/block/md126/md/array_state).


As I already said, adding mdmon to the initrd did the trick for me. Any
ideas about what I might have done wrong?

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

2010-12-19 Thread Rainmaker
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-user/454103-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:

No, not booting on a specific setup is bad, but doesn't render it

Please reread the severity explanations.
