I’m familiar with the lvextend
command but it won’t work in this case. Do I have to create a partition to get the unallocated space into the LVM?

Expand the /dev/sda2
partition with parted/GParted.
Expand the /dev/sda2
PV:
sudo pvresize /dev/sda2
sudo lvextend -r -l +100%FREE /dev/VGNAME/LVNAME

There’s only 8.00MB left on /dev/sda2
. How do I get the unallocated space noted from the screenshot? Do I need to create a partition for that?

You can resize the /dev/sda2
partition using the following free space, which is unallocated 261.19 GiB on your screenshot.

Well that didn’t work. Only added the 1 MB.

In GParted, did you try right clicking on /dev/sda2 and clicking “Resize”?

Sorry missed that step as well as running the actual operation in GParted.
pvresize /dev/sda2

Finally:
df -h

All good now. Still have to test a reboot.
Side question, why this warning?
