In This tutorial is write "To regain unique UUIDs, use "tune2fs /dev/sdbX -U random" on every partitions."
Ok, but how can I use with this command?
dd if=/dev/sda of=/dev/sdb bs=4096 conv=notrunc,noerror
Or I have to use after dd comand?
Thanks!
You example command copies the entire disk sda over the disk sdb. Every partition on sdb will have the same UUID as the original partition. If you want to change the UUIDs, you'll have to issue the command
tune2fs /dev/sdbX -U random
for every partition on the disk sdb (where X is the partition number starting from 1).
This, of course, assumes that you have an ext2/ext3/ext4 file system on these partitions.
