Recovery nepomohlo a přehrát grub se mně taky nedaří. Nabootuju ubuntu z CD a spustím příkazy:

root@ubuntu:/home/ubuntu# mdadm --assemble --scan
mdadm: /dev/md127 has been started with 4 drives and 2 spares.

root@ubuntu:/home/ubuntu# vgchange -a y vg
  3 logical volume(s) in volume group "vg" now active

root@ubuntu:/home/ubuntu# mount /dev/vg/root /mnt

root@ubuntu:/home/ubuntu# mount /dev/sda3 /mnt/boot/

root@ubuntu:/home/ubuntu# for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done

root@ubuntu:/home/ubuntu# chroot /mnt/

Bohužel toto mně vypíše chybu ať to použiji na jakýkoliv disk


ubuntu:/# grub-install /dev/sda error: superfluous RAID member (4 found). error: superfluous RAID member (4 found). Segmentation fault (core dumped) 

ubuntu:/# update-grub2
error: superfluous RAID member (4 found).

Verze GRUBU

ubuntu:/# grub-install -v

grub-install (GRUB) 1.98+20100804-14+squeeze1

Pole mám složené:

Již jsem i vytvořil další partition s ext2 na boot:

ubuntu:/# gdisk -l /dev/sda
