I had a perfectly normal Fedora 8 system running happily with a RAID1 / and /boot. After updating the BIOS to diagnose a potential disk problem, the boot sequence doesn't get very far.
The POST runs, the GRUB menu is displayed, and boots the default kernel. Then I get this:
Booting 'Fedora (188.8.131.52-57.fc8)'
Filesystem type is ext2fs, partition type 0xfd
kernel /vmlinuz-184.108.40.206-57.fc8 ro root=/dev/md1 rhdg quiet
[Linux_bzImage, setup=0x3000, size=0x205da0]
Decompressing Linux... Parsing ELF... done.
Booting the kernel.
Red Hat nash version 6.0.19 starting...
mdadm: no devices found for /dev/md1
mdadm: no devices found for /dev/md2
EXT3-fs: unable to read superblock
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
...and that's where it stops.
I only use md's. I do not use LVM.
I have booted with the rescue CD, and surprisingly it finds all the disk devices, assembles the raid devices and mounts everything just fine. The /etc/mdadm.conf is set up correctly, verified with a
mdadm --details --scan
From the rescue shell, I have tried running:
# chroot /mnt/sysimage
# /sbin/mkinitrd -v /boot/initrd-220.127.116.11-57.fc8.img 18.104.22.168-57.fc8
...and rebooted to exactly the same error.
I have tried reverting to the previous version of the BIOS to no avail. So I once again upgraded the BIOS and it now has the latest version.
Where do I go to from here?
Thanks for any help.
