error when copying/cloning partition

Post by sadhu » Wed Jul 18, 2018 4:31 am

I have a spare partition on my laptop into which I want to place a cloned image of LM17-64 from my desktop. The desktop and laptop are connected via LAN. Both machines are running LM18 and have their LM 17 partitions mounted using nemo.

On the laptop, I did rsync twice, because I notice that some files seem to be missing when I only rsync sadhu@: or just plain rsync -av 192....
sudo rsync -av sadhu@192.168.0.114:/media/sadhu/LM17/ /media/sadhu/newLM17
sudo rsync -av root@192.168.0.114:/media/sadhu/LM17/ /media/sadhu/newLM17

Then on the laptop I issued the blkid command to find the new UUIDs.

On the laptop I then used sudo xed /media/sadhu/newLM17/etc/fstab to update all of the UUIDs.

On the laptop I executed sudo grub-mkconfig, then update-grub.

When I reboot the laptop, LM 17 is visible in the grub menu. But when I boot to it, it times out and drops to a shell, with this error message
ALERT! /dev/disk/by-UUID/<old UUID of LM17 on desktop> does not exist.

In the shell, I execute ls sudo /dev/disk/by-UUID and all of the new, correct UUIDs appear, not the old 'bad' one from the desktop.

What do I have to do in order to boot LM17 on the laptop?

I think the problem is with grub.cfg. Here's the offending portion of grub.cfg

Code: Select all

if [ "${timeout}" = 0 ]; then
  set timeout=10

### END /etc/grub.d/30_os-prober ###

The correct UUID is 8e2c757e-a801-4a93-a03f-c8a7ae816639; however,some lines contain "UUID=62e2353c-3229-4d59-95dc-c5521bcd1459" which is the old UUID from the desktop.

I have a DOS partition at the beginning of the partition table. It was put there automatically when I installed--as I recall, it had to do with something about UEFI. Perhaps this is what it confusing grub.

Two additional things are required:

There's a file /etc/initramfs-tools/conf.d/resume that contains the UUID for resuming from suspend.

Change that then you'll have to chroot to the cloned system and rebuild the initrd.img for the kernel you're booting to with update-initramfs :wink:
