sudo lvextend -L +1G /dev/mapper/ubuntu--vg-ubuntu--lv

Size of logical volume ubuntu-vg/ubuntu-lv changed from 5.00 GiB (1280 extents) to 6.00 GiB (1536 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.

多执行几次,直到

Insufficient free space: 256 extents needed, but only 255 available

sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv 8G
