@momurda Huh.
lvextend -l +100%FREE -r /dev/mapper/centos-root
Seems to have done it.
I swear I ran the command multiple times. I suspect I was missing the "+" on "+100%FREE". I wonder what the difference is?
When creating an logical volume, you tell it how much space to use. While when making a change to the logical volume you need to tell it how much to add or remove. Thus the + or - when using lvchange, but not needed with lvcreate.
