InnoDB Database Using All Disk Space

I have a database for an app, that is currently using MariaDB with about 220 InnoDB tables. The entire database is about 30GB of data. However when attempting to move it to a new server that has the most recent MariaDB version I find that the database is consuming all available disk space (which is currently 800GB). I know that InnoDB can be expected to use 2-3x the database by size but that is like 26x the size of the database. What could be causing this issue? Below is what my config file looks like. This is the only thing I am running on the database server at this point so it has to be this database causing the issue. Any thoughts on what is going on?
