Ubuntu - MongoDB service won't start

Trying connect to a dev's environment MongoDB (3.6) ubuntu server fails, after digging around I've found the the MongoDB service crushed and fails to restart, getting the following error:

(code=exited, status=14)

Digging deeper into the logs the following error appears:

Unable to start up mongod due to missing featureCompatibilityVersion document.
Please run with --repair to restore the document.

Running mongod --repair, seems the process finish successfully, but trying to start the service again still fails with the same error.

Is there a way to fix or get around it?

If not, is there maybe a way to export the data so I can reinstall mongo and import it to the new installation? I don't mind reinstalling mongo from scratch, just don't want to lost all the data.

Apparently the issue with the mongod --repair was that the service and the command looked at different dbpath.

Specifying the --dbpath flag to the --repair command fixed the issue :)
