Resize root filesystem on Ubuntu 18.04 with LVM

Posted on December 24, 2018 by SoCRaT

Ubuntu 18.04 default lvm layout comes with only a 4 GB root partition. Here we will extend it to occupy the full free space in the volume group:

sudo lvextend -l 100%FREE --resizefs /dev/ubuntu-vg/ubuntu-lv

That’s it, Enjoy!

    This is missing a ‘+’ sign. When I used this it just increased the disk to 100GB. This will only affect users expanding over 100 GB,

    sudo lvextend -l +100%FREE –resizefs /dev/ubuntu-vg/ubuntu-lv
