After just the usual system upgrade using aptitude upgrade and system reboot, the connection to the server became unavailable. We connected KVM to it and the screen displayed: error: symbol not found grub_divmod64_full
A fast solution.
1. boot from a LiveCD (that's correct, you can do it in this Data Center…);
2. execute: mount /dev/md2 /mnt; mount /dev/md1 /mnt/boot; mount —bind /dev /mnt/dev; mount —bind /proc /mnt/proc; mount —bind /sys /mnt/sys; chroot /mnt;
- change /dev/md2 to your own root disk device (/);
- change /dev/md1 to your own boot disk device (/boot);
3. grub-mkconfig -o /boot/grub/grub.cfg; grub-install /dev/md1; update-grub;
- change /dev/md1 to your own boot disk device (/boot);
4. reboot.
