title: what is /data/configdb path used for in mongodb?
body: <p>I am running a docker of mongodb, and notice a volume created and mounted to /data/configdb. this is in addition to another volume mapped to /data/db which I know is where my actual data is stored.</p>
  
  <p>I am trying to find out what is stored in /data/configdb, and searched google for it. surprisingly enough I didn't find anything explaining what is stored there.</p>
  
  <p>what is stored there (/data/configdb), and can it be discarded everytime I restart my mongodb container?</p>
