Ubuntu LVM regrets

Thom_0203 · November 27, 2020

Hey

So I set up Ubuntu server on a new server and am currently struggling to understand LVM.

I was able run the following:

sudo lvextend -l 100%FREE /dev/ubuntudevbox2/root

And it resulted in this:

446GiB in size, but 181 of 196 Gib used... Its limited for 196 GiB for some reason. Does anyone have a suggestion on how to fix this?

Thanks in advance!

What you did extends the logical volume, you still need to expand the partition's filesystem. You can't do that while it's mounted so you'll need to boot from a tool like gparted.

You need to run resize2fs on the filesystem. Boot off a USB-stick, run resize2fs /dev/yourpartition.
