Hi,
I've decided to upgrade to kubuntu 9.04(64bit) from kubuntu 8.10(64bit)
on the following system :
P5N32-E Sli plus motherboard
C2D 6250
4GB of RAM
2x 250GB SATA, RAID1 software for linux (sdc, sdd)
2x150GB Raptor SATA Raid0 for windows (fake raid from motherboard) (sda, sdb)
I run as told the "update-manager -d" command.
Nothing to report on the upgrade (just ask me what to do with the vim conf file).
The system was running well before the upgrade (and as already been upgraded from 8.04 to 8.10)
On reboot I have this message:
no block devices found (4 times)
Gave up waiting for root device.
ALERT! /dev/md3 does not exist. dropping to a shell!
I've tryed to reboot with the fake raid for windows disabled (hard drives unplugged). no change.
on busybox (which I get after the errors):
in dmesg output I can see these kind of message:
sdd : sdd1 sdd2 <<6>attept to access beyond end of device
sda: rw=0 want=586067137, limit=293046768
Buffer I/O error on device sda1, logical block 293033536
(but these kind of message appears on gparted livecd)
in ls /dev, I can see the and sdcX sddX partitions are here.
I've no clue on how to bring my system back...
any Idea ?
when I'm on busybox,
if I do mdadm --assemble --scan I get the md 0,1,2,3 of my system
So I tryed to chroot and reinstall grub :
mkdir /mnt
mount -t ext3 /dev/md3 /mnt
mount -o bind /dev /mnt/dev
mount -t proc none /mnt/proc
mount -t sysfs none /mnt/sys
mount -t ext2 /dev/md0 /mnt/boot
mount -t ext3 /dev/md2 /mnt/var
chroot /mnt /bin/bash
grub
grub>root (hd0,0)
grub>setup (hd0)
grub>quit
with no luck...
I then tryed (after chroot) to
/usr/sbin/grub-install -–recheck /dev/md3 –-root-directory=/
but it won't work (I guess the /dev/md3 is wrong... i've tryed some other thing like /dev/sda with no luck)
I really need some help... I've no other idea...
