RAID1 na Ubuntu 12.10

Ahoj

Snažím se udělat RAID1 na již běžícím systému, postupuji podle návodu zde: http://www.howtoforge.com/how-to-set-up ... untu-10.04

ale poté co dám instalaci grub na /dev/sda a /dev/sdb a restartuji tak již system nenajede. Zkoušel jsem rady z komentařu pod tím návodem ale nic nepomohlo a už nevím jak dál s tím tak prosím o radu.

Po restartu

error: file "/boot/grub/i386-pc/raid.mod" not found
error: file "/boot/grub/i386-pc/mdraid.mod" not found
Loading Linux....
error: disk "md/0" not found
Loading initial....
Error you need to load the kernel first

Press any key to continue

Zkoušel jsem kombinovat i s navodem zde http://www.pc-pingan.com/index.php?mod= ... ew&id=4451

Napadá mě už snad že by mohla být chyba při vytvoření md0 když mě to upozornuje tímto a dám yes a vytvorit i pres to:

Note: this array has metadata at the start and
may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90

Ale moc nechapu co to znamena a jak to vyřešit.

Disk ze kterého načíta Ubuntu je:

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders, total 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00023f2d

Device Boot Start End Blocks Id System
/dev/sda1 * 2048 18874367 9436160 83 Linux
/dev/sda2 18876416 20969471 1046528 82 Linux swap / Solaris

Dále přikladam jak mám nakonfigurované soubory:

# the 'exec tail' line above.
menuentry 'Ubuntu, with Linux 3.0.0-17-generic' --class ubuntu --class gnu-linux --class gnu --class os {
insmod raid
insmod mdraid
insmod part_msdos
insmod ext2
set root='(md/0)'
echo 'Loading Linux 3.0.0-17-generic ...'
linux /vmlinuz-3.0.0-17-generic root=/dev/md0 ro quiet
echo 'Loading initial ramdisk ...'
initrd /initrd.img-3.0.0-17-generic
}

a nakonec jsem ještě upravil: /etc/default/grub

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
GRUB_DISABLE_LINUX_UUID=true
