Two problems I can imagine:
- the two disks will have partitions with identical UUIDs.
I was thinking the purpose of the cloning was to replace one drive with
another. If you are cloning a drive and keeping them both in the machine it
will be a problem if you are referencing drives by UUID. You can always
change the drive ID after the cloning process by referencing it by
filesystem ID. The fstab file in my machine uses filesystem ID for drive
references. The only time I use device UUID is in grub2. Back in the days of
grub1 I had it using the filesystem ID.
- if the geometry is different you might get a bad result.
If the size/type of drive is radically different that could be a problem. In
that case the new drive can be partitioned as desired (ie. like the old
one), then rsync can be to copy the files.
