Having issues resizing /dev/mapper/pbs-root

Maybe you forgot the resize2fs part to extend the filesystem to the new LV size?
Oh my gosh. I think i did do that originally but i followed the pve command that he was showing and didn't think about it and do resize2fs /dev/mapper/pbs-root. After I ran that command it immediately fixed the issue. Thank you @Dunuin. I was literally one line away from a solve.
