Invalid path for Logical Volume when resizing

Question

I'm new to Centos 7 but I'm trying to move space from the home directory to the root directory. I'm using this question for reference: How to move disk space from centos-home to centos-root

Does anyone know what I'm doing wrong?

UPDATE:

[root@ns537316 /]# lvscan
[root@ns537316 /]# pvscan
  No matching physical volumes found
[root@ns537316 /]# lvscan /dev/md3
  Command does not accept argument: /dev/md3.
[root@ns537316 /]# pvscan /dev/md3
  Command does not accept argument: /dev/md3.
[root@ns537316 /]# pvscan /dev/md3/

You are trying to do something you don't understand. /dev/md3 is not an LVM volume but a mdraid software RAID device that can't be managed with LVM. Please edit your question to add the output of lvscan and pvscan and do not post screenshots but instead, copy/paste the information into the question and use the formatting tools. — Sven, Oct 15 '17 at 16:31
@Sven Exactly why I said I was new to Centos 7. I did lvscan and pvscan and nothing popped up. I edited my question to show the results — DarthVegan, Oct 15 '17 at 16:34

You are not using LVM so you can't do what you want. In your setup, doing this is so complicated (if possiblbe at all) that I would strongly suggest to not even try it and instead back up everything and start over with useful partition sizes (and LVM)
