Lvextend no encuentra espacio libre

Estoy tratando de expandir mi partición lvm en Ubuntu 16.04, pero

lvextend -l +100%FREE /dev/Server0-vg/root 

muestra

 New size (3861 extents) matches existing size (3861 extents) Run `lvextend --help' for more information. 

Mi partición lvm es / dev / sda5 y está en / dev / sda2; ambas son 159GB. lvdisplay muestra:

(Si alguien no obtiene, quiero expandir / dev / Server0-vg / root a 159 gb)

df -h muestra:
