Manjaro MySQL - mariadb.service fails to start

When trying to start MariaDB with systemctl status mariadb, I get:

Having followed various tutorials, I may have made it worse. I cannot run mysql anymore (in the context of mysql < file.sql), since it says mysql: command not found. I have tried removing, reinstalling mariadb and rebooting my computer in between; but I'm out of luck. Any ideas? **EDIT:** Many others seem to be having this problem, . Not sure what else I did next as it has been over a year. I do know that following the installation guide [Arch Wiki](https://wiki.archlinux.org/index.php/MariaDB#Installation) page LINE BY LINE will guarantee a proper install. The formatting of the page made me read over things (important things were small, optional things were bold), but make sure you do that right and your installation should work.
