I have a **1T USB** disk with Fedora 20 installed. It shows as **sdd** in the first image below. I only used about 50GB. There are 3 logic volumes under the sdd2 and also there are about 620GB of free space after I shrunk its **home** logical partition, as shown in the second image.

I am thinking **create a physical volume/partition, sdd3, by using that 620GB free space**. I hope other logical volumes will not be damaged and **data will stay unchanged**. how can I do that?

I have created a disk image with clonezilla. So I am not worry about data loss during the process.

The purpose of doing this is I want to move the installation on my 1T disk **with settings** over to my another 500GB USB disk. I have tried many ways, clonezilla, **dd** logical partition(s), true image, gparted, .... no one can help me or gives me a good result due to the lvm and smaller destination. I hope I can dd physical partition after the new physical partition takes over some space.
