As you can see on the image above it has a 100G LVM. is there a way to expand this to use up say 1.2Tb leaving the rest for ubuntu
I have no idea on the problem, could you possibly please copy the txt of the bash output and edit or reply to your post adding it to this forum post.
Just a straight paste of the output then it will be easier search with a search engine.
