Before or during the restore you have the opportunity to modify the 
disk layout (disklayout.conf). It is documented in the User Guide at:


If the User Guide is confusing or ambiguous, or you know how to improve 
it, please send us a pull request with the improvements. It helps 
tremendously to get feedback from actual users and use-cases.

But after the restore has completed, you can also resize the partition 
(fdisk) and PV (pvresize), or extend the VG (vgextend) as you please.
It basically depends whether you want to restore ASAP (and fix later) in 
DR mode or you have the time to investigate and adapt during restore 
(e.g. during a planned migration).
