My PC has a 500GB hard disk, and I want to migrate it to a 2TB hard disk. The new hard disk has been formatted to have two physical partitions, one serves as /boot and the other is an encrypted LVM volume, which has its own division into logical partitions.
I rsync'ed the old hard disk's contents into the new one (excluding - /lib/init/rw/*** - /dev/shm/*** - /proc - /sys - /tmp/*** - /var/lock/*** - /var/tmp/*** - /cdrom/*** - /media/*** - /etc/fstab ). I edited /etc/fstab in the new hard disk to specify the correct partitions. Then I ran grub-install on the new hard disk using: chroot /tmp/new_2T grub-install /dev/sdb where the new hard disk's /boot and logical partitions are mounted on subdirectories of /tmp/new_2T, and the new hard disk itself is /dev/sdb. However the logical volume paths in the old hard disk and the new one differ. It turns out that the kernel and initrd images in the old hard disk have the old logical volume paths hardwired in them. So when trying to reboot the PC from the new hard disk, it doesn't find the root filesystem. The failing script is /scripts/local-top/cryptroot (/scripts/local-top template can be found in /etc/initramfs). So it seems that I need somehow to recreate the initrd.img's contents. I may have missed also other things. Questions: 1. How to recreate initrd.img's appropriate for the new hard disk? 2. Is there any guide about migrating a Debian Squeeze system inside an encrypted LVM partition from one hard disk to another hard disk? In conclusion: I am dismayed at the fact that migrating Linux systems, which used to be a simple affair (like MS-DOS), is now complicated (like versions of MS-Windows after Windows 95).
