You need to format the EBS volume (block device) with a file system between step 1 and step 2. So the entire process with your sample mount point is:

Create EBS volume.

Attach EBS volume to /dev/sdf (EC2's external name for this particular device number).

Format file system /dev/xvdf (Ubuntu's internal name for this particular device number):

sudo mkfs.ext4 /dev/xvdf
Mount file system (with update to /etc/fstab so it stays mounted on reboot):

- Creating new index with ttl, the key must be date type and can not be a compound index.

> db.teste_ttl_idx.ensureIndex({ttl: 1}, {expireAfterSeconds: 5});

- Insert new documents
> db.teste_ttl_idx.insert({ttl: new Date()});
> db.teste_ttl_idx.insert({ttl: new Date()});
> db.teste_ttl_idx.insert({ttl: new Date()});

- You can do a find all to check if the elements were inserted and if they will be removed in the next 5 seconds after their creation.
