Hi @tamburrinipietro89

The error is error command line: unrecognized line in 'storage:'

Can you post your /etc/systemd/system/mongodb.service and /etc/mongod.conf since one of them must have a reference to storage:

There's a mongod.log file but it only say things about data received qhen the db was working. Anyway i once runned it with sudo wich isn't a good practice, can be that i introduced some locks or things like that? I tried to uninstall and make a fresh install but nothin. Is there a way to remove mongodb and everything like it was never installed? Im yelling angains the terminal since a week or two

    I see your mongod.conf file.
    Just try to change your dbPath after creating new db path.

    first run
    sudo mkdir -p /data/db

    then change your dbpath.
    dbPath: /data/db

    This will solve your problem.
