      The system is saying that xvda2 is mounted.

      Yet I have no idea how it's mounted.

      So, just grep /etc/mtab for xvda2.

          So, I think you can safely force the pvcreate.

              Oh, xvda2 is your root filesystem. What's the output of fdisk -l? It looks like it should be xvda3

              xvda1 is the boot partition.

                  Did you create a partition for the free space? You need to use fdisk to make a third primary partition.

                      Dumb question, would it be easier for me to simply add a separate drive, and then extend the root drive into the new drive?

                        Maybe.
                        You can skip the fdisk stuff and add a whole new block device to LVM if you add another virtual disk.

                          @Francesco-Provino I'm fine with a separate physical device, so long as the system uses it as a single device.

                            You can actually move everything to the new drive using lvm. Tho I don't remember how to do that offhand, I'd have to look it up.

                              OK so this is what I have with a new "physical" drive attached to this VM.

                                      You don't want to extend a pv tho, you want to create a new one. Add the new pv into the current vg (volume group), and then extend the lv (logical volume) to fill the new pv.

                                      pvcreate /dev/xvdb
                                      vgextend fedora /dev/xvdb
                                      lvextend -l 100%FREE /dev/fedora/root
                                      

                                      See if that lvextend works, might need to feed it another vg/pv path.

                                            @DustinB3403 Now you need to figure out why your root partition got filled up in the first place!
