LVM thin pools are great. I love them. They offer a great deal of flexibility especially combined with autoextend functionality. The idea is to keep your pools as small as possible and let them autoextend whenever needed. So if the pool is always as small as possible, why do you need to shrink it?

Why?

As I frequently reinstall my OS (for various reasons) but in the mean time I still want to be able to access my old OS for daily use, I do a lot resizing of filesystems and partitioning of my hard disk. When the time has come to use the new OS installation as a daily driver, I like to reclaim my old OS space so I can have all the space available.
