      root@server:/var# lvresize -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
      Size of logical volume ubuntu-vg/ubuntu-lv changed from 4.00 GiB (1024 extents) to <99.00 GiB (25343 extents).
      Logical volume ubuntu-vg/ubuntu-lv successfully resized.

      🙂 Now what?

              I still need to resize the file system I believe?

                Seems like I should run:

                resize2fs /dev/ubuntu-vg/ubuntu-lv

                ?

                  @Curtis it depends on filesystem. That's why I asked for output of mount command.

                        It's ext4, so the above command you provided is correct.

                              So what you have is a file system (EXT4) inside of a volume on top of a partition, on top of the physical device. The issue was that the volume was the wrong size, so the filesystem was using all available space "to it", which was 4GB. The partition had a 4GB volume inside of the 100GB partition. So we had to expand that, then expand the FS to fill the new space.

                                That's pretty confusing. I'll have to read up on it more. Anyone have some recommended readings that might help me wrap my head around this?

                                  Not really. It is a simple logical design. Pretty much all systems work this way.
