extend a partition on linux

extend.md

using parted

parted
(parted) print
(parted) resizepart

partition number? probably get warned about the partition being used... be strong set the end to the biggest number you can think of

then quit out of parted

you'll probably need to use resize2fs to get the disk to recognize the new partition size

unless Ubuntu is using a logical volume manager

sudo fdisk -l

sudo pvresize /dev/sda3
sudo lvextend --size 54G /dev/mapper/ubuntu--vg-ubuntu--lv
sudo lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
