After expanding the size of the disk on my Proxmox hypervisor from 8GB to 18GB I am trying to see this new space on my Ubuntu 20.04 VM: enter image description here

These are the commands I'd run on the VM

# Physical volume is called /dev/sda3
sudo pvs

resize the Physical Volume (PV)


sudo pvresize /dev/sda3


root logical volume is


df -h


expand the logical volume


sudo lvextend -r -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv


resize my number 3 partition (this gave me 17GB on sda3)


sudo growpart /dev/sda 3

enter image description here

I can see it on the sda3 partition!

enter image description here

Want to see the 18GB on /dev/mapper/ubuntu--vg-ubuntu--lv

https://unix.stackexchange.com/a/583544 - am following these instructions

Any pointers would be great!

https://packetpushers.net/ubuntu-extend-your-default-lvm-space/ was the article which helped me the most.

In summary

# allocate more space on hypervisor

make the partition see the space (dev/sda3, Resize, Write, quit)


sudo cfdisk


extend the physical volume from the partition


sudo pvresize /dev/sda3


extend LV to use up all space from VG


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


resize file system


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


check can see the space on filesystem


df -h

Do the following to increase volume size.

  • Increase/resize disc from GUI console

  • Identify Linux partition:

    sudo fdisk -l

  • Extend physical drive partition

    growpart /dev/sda 3

  • Instruct LVM that disk size has changed

    sudo pvresize /dev/sda3

  • Find Entry with starting LV

    lvdisplay

  • Resize LV

    sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
