You should stop the mongodb first:
service mongodb stop
rm -rf /var/lib/mongodb/journal
service mongodb start
Additional hint: you could limit the journal to 128MB by adding smallfiles=true to the config file /etc/mongodb.conf.
Solution taken from here and tested on Ubuntu 16.04.

Thanks man. I realized it after some googling. Nevertheless, thanks a lot of pointing it out. – Biscuit Coder Mar 31 '17 at 07:51

No need to restart mongod service - this is not good solution sometime. There is more simple solution if you just want to cleanup the single log file:
echo '' > /var/lib/mongodb/journal.log

That cannot be right. `/var/lib/mongodb/journal` is a directory. – Tilman Schmidt Aug 31 '21 at 09:48

Original question was about a file, not about directory. So, i assume /var/lib/mongodb/journal this is a path to file. I just based my answer on previous question path - but answered original question – Igor Benikov Sep 01 '21 at 12:41
