[SOLVED] disk-by-id

[phsieh2005]

Dear Linux experts:

I installed OpenSUSE 11.2 on a computer. I would like to clone the hard drive so that I can put the same disk image on another computer with the same hardwares.

I used clonezilla to create the hadr disk image, when I restore the image on another computer, I got errors and failed to boot. I later learned that, I have disk-by-id on /etc/fstab and grub/menu.list. So, I went into the computer that I tried to restored using Knoppix liveCD and manually changed the fstab and menu.list so that it used something like /dev/sda1, /dev/sdd2, and /dev/sda3, instead of /dev/disk/by-id/WD....-part1 (part2/part3). When I re-booted the new computer, it still failed to boot.

So, do I have to go back to the original computer, manually edit fstab and menu.list to /dev/sda1 /dev/sda2 /dev/sda3, then re-create the disk image? Is there anything I have to change so that it does not use disk-by-id any more?

Thanks!

Pei

That should have worked. The disk-by-id is just pointers to the device sdx#. Maybe you did something wrong, Show the menu.lst file here maybe some one will spot the problem.

Dear gogalthorp,

Thanks a lot for the suggestion! As usual, you are very helpful. I found out that I did make mistakes when editing both fstab and menu.lst. This computer actually has 3 hard drives. I thought that the OpenSUSE drive will naturally be sda. But, it turns out it was assigned sdc. So, I re-edited fstab and menu.lst to use sdc (instead of sda), not, it boots to OpenSUSE 11.2 without any problem.

Best Regards,

Pei
