Mongo can't connect

I'm running Ubuntu 15 on an Azure VPS. I installed MongoDB and got it up and running fine. Then, I stopped the mongod service and I changed the db path and log path in mongod.conf to point to directories I've created on an attached disk:

# Where and how to store data.
storage:
  dbPath: /datadrive/lib/mongodb
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /datadrive/log/mongodb/mongod.log

I restarted the entire VPS to make double sure the new changes take effect. Now when I type mongo I get the following error:

2016-02-05T14:49:41.004+0000 W NETWORK  [thread1] Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2016-02-05T14:49:41.018+0000 E QUERY    [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:224:14
@(connect):1:6

If I reverse my changes and use the original log and lib locations, it works. What can I do to make sure the new locations are used?

Edit

After keeping the old log location and trying the above steps, I get the following in the log:

First of all you can check if mongod started: sudo lsof -i | grep 27017 and then check what's in the log /datadrive/log/mongodb/mongod.log.

EDIT:

Stop all instances of mongod (ps aux | grep mongod should show nothing's running), remove lock file rm /datadrive/lib/mongodb/mongod.lock, and restart the service.

EDIT2:

Directories from the config /datadrive/lib/mongodb/ and /datadrive/log/mongodb/ should exist and belong to mongodb user. By default it is mongodb:mongodb, and is defined in /etc/init.d/mongodb as DAEMONUSER.
