I'm running Ubuntu 10.04, and planning to upgrade. Before I do, though, I want to make sure my backup/restore processes work. My backups, of course, have been running since I first installed 10.04, but it's only a restore that can demonstrate that they have been running successfully.
And I've found a problem. I don't know how to get grub2 configured correctly, on the restored disk. Currently, my running system is on /dev/sda, with /boot on /dev/sda1 and / on /dev/mapper/desktop-root. (I'm using logical volumes.) This configuration has been running successfully for several years. My restore is on /dev/sdb, with /boot on /dev/sdb1 and / on /dev/mapper/desktop2-root. All of the files have been restored, and /etc/fstab has been edited, on the restored drive, to reflect the changed logical volume name. But I only have grub installed on /dev/sda, so /dev/sdb is not bootable. I'm not looking to do anything fancy. I'm not trying to dual boot, I just want to be able to boot from /dev/sdb, using /dev/sdb1 as /boot, and /dev/mapper/desktop2-root as /. In other words, I want to do to /dev/sdb exactly what running update-grub would do to /dev/sda, when I was booted off of /dev/sda. Any ideas? _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
