Change UUID of the Cloned Disk in linux

Madeswaran N
 
If you’ve cloned a disk, such as by using dd, you might want to be able to mount both the original and the clone at the same time. To make sure that the UUIDs don’t clash, first generate a new UUID, and then assign it to the new disk with tunefs:

  #uuidgen
... 79fb806d-4350-4b8c-8bc3-f3bb0c6b56f2

  #tune2fs -U 79fb806d-4350-4b8c-8bc3-f3bb0c6b56f2 /dev/sdc1

Now mount the new disk:

#mount -U 79fb806d-4350-4b8c-8bc3-f3bb0c6b56f2 /mnt/clonedis

    On debian/ubuntu system, you have install the following packages inorder to use this command.

    #apt-cache search uuidgen
    uuid-runtime - runtime components for the Universally Unique ID library

    #apt-get install uuid-runtime

    #uuidgen

    Only works on ext partitions. What about when you've cloned something else (like linux_raid_member_disk)?
