SATA RAID 0 errors on bootup -- invalid raid superblock

vonst · 05-22-2006, 07:58 PM

I've been working on a new install of the 10.2 disks. The following has been keeping me from finishing my install! To start, here's my system:

NForce4U chipset on BFG mothergboard (4 SATA2 / RAID enabled)
nvraid (fakeraid) turned off.
3 WD2500 SATA HDD's + 1 WD3200 SATA HDD.
AMD Athlon 3200+

My RAID partitions are: /dev/sda1 + /dev/sdb1 + /dev/sdc3 + /dev/sdd1

Interesting note: the BIOS and WinXP (on another partition) see /dev/sdc as my 1st disk, but Linux sees /dev/sda as the first disk. I think it has something to do with SATA...

I was successful in creating /dev/md0. I actually installed Slack 10.2 into it. But I can't find it on boot, because I can't mount the partitions at boot. I can "mkraid" them back, every time I boot from the install disks, and Slackware is still there. The following is from the install disk load of "sata.i". The same thing happened with the LILO /boot install of sata.i and a 2.6.16.4 kernel I compiled on a differnent machine and moved over to the /boot directory.

Can someone look at this 'dmesg' for me and tell me why it can't find those superblocks?

I may not be much help, so I was going to PM you so this stayed as an "unreplied thread" and kept getting attention, but that's disabled. PM is handy sometimes...

Anyways, care to post your LILO config? And you are working with a custom kernel? What are the setting it has? If you are doing software raid, the raid drivers may require the filesystem driver to be loaded (I don't know RAID), so are the required filesystem modules loading before the RAID drivers? Also, don't forget to set your /boot partition separate from the raided partition.

Oh the little tricks I've learned! This is indeed why I am fiddling with this new concept.

In answer to the questions: I am using 10.2 install disks with the sata.i kernel. By using them, I can get to the CLI and (through a complex procedure that I've mostly automated) mkraid /dev/md0. That gets me to my RAID0 partition. /dev/md0 has a full vanilla install of Slack 10.2 on it. I generated a 2.6.16.16 kernel with NO MODULES. I put sata_nv in it and I turned on RAID 0. It's entirely possible that I didn't do everything I needed. I transferred that kernel from its "build computer" to its "use computer." Then, I made a special lilo menu line to load it. I also made a lilo line to load the /boot/vmlinuz -> /boot/sata.i kernel from the disk.

I can't hotplug my thumb drive into the USB port when I load Linux with the install disks. I just found out, however, that when I chroot into my RAID0 partition (which I mount as /raid: chroot /raid), all of the sudden I can mount my thumb drive! I didn't know that before!!!

So, since I can do that now, I've got my lilo.conf. Here it is:

Quote:

# LILO configuration file
#
# Start LILO global section
boot = /dev/sdc
prompt
timeout = 300
# VESA framebuffer console @ 1024x768x256
vga = 773
# ramdisk = 0 # paranoia setting
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/md0
label = Linux
read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
# Windows bootable partition config begins
other = /dev/sda1
label = Windows
table = /dev/sda
# Windows bootable partition config ends
# Another Linux bootable partition
image = /boot/toot/vmlinuz
root = /dev/md0
label = Special.kernel
read-only
# Linux bootable partition config ends

As a post note: I switched around my devices. cwwilson stated that I needed to put LILO on the first device. Consequently, I now run lilo -b /dev/sda because boot=/dev/sdc. Two days ago, it was reversed. It doesn't seem to matter, the answer is still the same.

*** SOLUTION *** SOLUTION *** SOLUTION ***

Thanks to everybody that helped me figure out this complicated and logic-defying problem.

I found the solution in the old Software-RAID-HOWTO, while searching for instructions for and applications for mdadm.

I installed Slackware on a single partition, ran mdadm, and have had a persistent /dev/md0 since! Here's the code I used:

Code:

mdadm --create --verbose /dev/md0 --level=raid0 --raid-devices=3 /dev/sdb2 /dev/sdc2 /dev/sdd2
