Hello, I really struggle since days, running systemctl start mongod.service - as it always hangs up. I can cancle the command with ctrl+c. The funny thing is, that the mongodb server is reachable and I can filter, add and delete items. The problem is, that when I run sudo systemctl status --full --lines=50 mongod I get following output:

As you can see here, “Active” is remaining on “activating” and is not changing at all. That is why the command hangs, and that is, why other services, which should run with After=network.target mongod.service does not run at all, as mongod is never finishing the start up…
Here is my config - pretty much default, I only changed the dbPath to create a new one.

It would be really appreciated, if someone of you knows how to fix that problem, that systemctl start will run completely and Active: Running is appearing instead of Active: activating
Thank you in advanced!
