I have attempted to expand the volume of an Ubuntu 18.04 server running on vmware. LVM is in use. I shut it down, expanded the virtual disk in vmware, and powered it up. I then used cfdisk to resize the 40GB /dev/sda3 to the max of 199GB. That went fine.
Output of cfdisk after reboot: /dev/sda1 = 1M /dev/sda2 = 1G /dev/sda3 = 199G
I then ran df -h
Filesystem Size Used Avail Use% Mounted on udev 3.9G 0 3.9G 0% /dev tmpfs 798M 1.1M 797M 1% /run /dev/mapper/ubuntu--vg-ubuntu--lv 39G 4.0G 33G 11% / tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/loop0 90M 90M 0 100% /snap/core/8268 /dev/loop1 92M 92M 0 100% /snap/core/8592 /dev/sda2 976M 145M 765M 16% /boot tmpfs 798M 0 798M 0% /run/user/1000
I know I need to expand /dev/mapper/ubuntu--vg-ubuntu--lv so I tried
resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv resize2fs 1.44.1 (24-Mar-2018) The filesystem is already 10222592 (4k) blocks long. Nothing to do!

I also tried
lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv New size (9983 extents) matches existing size (9983 extents).
So my issue is that in cfdisk, it says /sda3 is 199G. However I can't figure out how to extend
/dev/mapper/ubuntu--vg-ubuntu--lv 39G 4.0G 33G 11% /
to fill the remaining ~160GB space on /sda3.
I would greatly appreciate any guidance. I was following the "faster method" here: Increase partition size on which Ubuntu is installed?
And now I seem to be stuck.
I should add that I also tried this, but it doesn't seem to like it on a mounted filesystem.
vgextend ubuntu-vg /dev/sda3 Can't open /dev/sda3 exclusively. Mounted filesystem?
