I read the great HOWTO (thanx for the people who did it).
Everything works perfect until i try to do the boot part:(
I have 5 raid5: /, /home, /usr, /tmp, /var. Besides i have 4 other
partitions, one on each disk (i've 4 barracuda disks). The first one, i
use it for /boot, and the other ones for swap. That 4 ones are not raids.
Well, i tried to do the lilo phase but i have probs with my stupid adaptec
raid controller (i can't choose which disk it's the boot one...only raids
) so i decide to boot from a floppy disk. I copied the kernel and loadlin.
The kernel begins to load everything...it reconizes all raids but at the
end, when it finishes reconizing all partitions i get the next message:
Kernel Panic! VFS: Cannot open root device 03:01
Btw, i copied all files inside /mnt/newroot (and of course, i
mount the other ones before/mnt/newroot/usr....) . I checked it already.
And i updated /mnt/newroot/etc/fstab and lilo.conf, although at the end, i
don't use that one.
Thanx in advance. I've tried some changes in the fstab but owing
to the kernel panic...next time i boot from the other hd, raid resyncs all
partitions and it took 40 min. Maybe someone knows how to fix it
Here it's my config files:
I'm using kernel 2.2.10 with raid patches.
