Not all the partition is being used: how to fix

[abasel]

sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

Gives

NAME                      FSTYPE       SIZE MOUNTPOINT LABEL
sr0                                   1024M
xvda                                    20G
├─xvda1                                  1M
├─xvda2                   ext4         1.8G /boot
└─xvda3                   LVM2_member 18.2G
  └─ubuntu--vg-ubuntu--lv ext4          10G /

I am wanting ubuntu--vg-ubuntu--lv to use all of xvda3 space available.

How do I do this?

Ah, I think I can simply boot using gparted disk and then expand it. Will try when back at desk.

You will find out that gparted cannot manage LVM devices. You need to use a terminal.
ubuntu-vg is your volume group - size 18.2G
ubuntu-lv is your logical volume - size 10G

One terminal command will do it:

sudo lvextend --resizefs --size 18.2G /dev/ubuntu-vg/ubuntu-lv

You can do from Ubuntu itself. That's a nice thing about LVM.

Awesome, thanks that worked a treat.
