Resize physical volume:
```bash
[root@awi-ci-01 ~]# pvresize /dev/sda3
Physical volume "/dev/sda3" changed
```
# pvresize /dev/sda4
Physical volume "/dev/sda4" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
#
```
Now the effective volumes of the machine can be extended as documented [Partitioning](partitioning.md)
