Hi

lvm2 cannot move 'individual' thin volume as this volume is 'just virtual' and 
uses chunks from the thin-pool.

So if you want use thinLV from a new faster storage - then whole thin-pool 
must be moved to the faster storage.

And when you will be doing this - move the also _tmeta volume.

(See 'lvs -a'  output for volumes you can move)
