\
restart mongo db

```
sudo systemctl start mongod.service
```

The order of volume matter : the first volume is by default the startup volume&#x20;

### How to know if a DB is empty&#x20;

* Conect to mongo using `mongo`
* Type `show dbs;`
* It will output all dbs and  their space on disk

### Start Mongodb from default location&#x20;

```
mongod --dbpath=/var/lib/mongodb
```
