RAID-0 Assembly Failing on Boot

**ecliptik** · 11-17-2007

For the past two months I've been running two 500Gb SATA drives (/dev/sda1 and /dev/sdb1) in RAID-0 (/dev/md0) and mounting it as /home on my 64-bit Debian Etch server. The OS runs separately off of an 80Gb PATA drive at /dev/hda. Unfortunately a few weeks ago my power supply failed and upon getting a new one and updating the linux kernel to 2.6.23.7 (it was working with 2.6.22) the RAID stopped coming up on boot. Even reverting back to the original stock Debian kernel (2.6.18-5) that the RAID was built with still gives the same errors.

The error message on boot is:

Code:

Assembling MD array md0...failed (no devices found).
Generating udev events for MD arrays...done.

and when I try to manually assemble the array with: mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 I get:

Code:

mdadm: cannot open device /dev/sda1: Device or resource busy
mdadm: /dev/sda1 has no superblock - assembly aborted

Which doesn't make much sense since /dev/sda1 and /dev/sdb1 are both detected in the kernel and even mdadm --examine shows they have valid RAID superblocks which match the UUIDs that are in /etc/mdadm.conf (see bug report output below). I've also checked for anything using /dev/sda1 and /dev/sdb1 (lsof, etc) but I can't find anything that would cause them to be busy.

After kernel recompiles, downgrading the kernel, updating Debian, tweaking /etc/mdadm.conf and /etc/default/mdadm.conf, and even searching the Debian bug archive I still haven't found a way for the RAID to load properly. However, after coming across this Ubuntu bug, https://bugs.launchpad.net/ubuntu/+s....15/+bug/27037, it gave me an idea. I loaded the RAID partitions as loop devices using losetup, assembled the array by hand, and then it mounted just fine, all the data was there.

Code:

losetup /dev/loop0 /dev/sda1
losetup /dev/loop1 /dev/sdb1
mdadm --assemble /dev/md0 /dev/loop0 /dev/loop1
mdadm: /dev/md0 has been started with 2 drives.
cat /proc/mdstat
Personalities : [raid0]
md0 : active raid0 loop1[0] loop0[1]
      976767872 blocks 64k chunks

unused devices: <none>

Could anyone explain what is going on here? Do I need to set some certain kernel parameters when building a custom kernel for RAID? I didn't do anything special, just the normal SATA modules for my chipset (VIA) and the standard RAID modules, nothing experimental. I've attached a zip file of the kernel config to this post as well.

Currently I have a script that loads everything correctly at boot, but I don't like the idea of having to go through a loop device when I know this has worked normally in the past. If anyone could help shed some light on this I would greatly appreciate it, thank you.

After finding some time to work on this again, I finally came across the solution. I have a VIA chipset that does "fakeraid" and in the VIA BIOS utility both drives were part of a "fakeraid" array. I removed this array, disabled the VIA RAID controller, and rebooted, only to see that the "Linux raid autodetect" partitions missing. I recreated these with fdisk and rebooted again to see a fully working software RAID.

Something very simple to fix, but at the same time confusing, hopefully this helps someone else out who has a similar issue.

How do I turn off the screen energy saving feature under Linux. Under Windows there is PowerOption in Controll panel that allows you to manage this feature. How about Linux.

My customer wants the screen to be on all the time. Thanks a alot in advance for your resonse/help/

Hi ecliptik,

It seems I have the same problem as you described in your post "RAID-0 Assembly Failing on Boot". Only one question: how did you find out that a "fakeraid" was already running. I don't see that in your processes or lsmod-lis
t. I have also a controller with software raid, but as far as I checked it, the RAID functionality is disabled. So I wonder whether there is any sign noticing that although being disabled, the fakeraid started nevertheless.

Many thanks,

linuxnomo
