Thanks Daniel. I have tried sudo lvextend -l+100%FREE /dev/mapper/ubuntu--vg-root (I think we did try this before). I received the following output:- New size (13736 extents matches existing size (13736 extents) Run 'lvexted --help' for more information. I did do this but it still left me clueless! I thought it best not to submit your second command until reporting back. Outputs from fdisk -l, pvdisplay and parted -l remain as previously reported.
