扩展卷组（VG）以使用新的空间

~$ sudo pvresize /dev/sda3
  Physical volume "/dev/sda3" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized

扩展逻辑卷（LV）

现在，可以扩展逻辑卷 ubuntu-lv 以使用卷组中的所有剩余空间。

~$ sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
  Size of logical volume ubuntu-vg/ubuntu-lv changed from <31.00 GiB (7935 extents) to <331.00 GiB (84735 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.

调整文件系统大小

sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
