(Only new volumes) Format the volume. WARNING: Do this step only for new volumes. Do NOT do this step for existing volumes, as it will wipe out the volume:
>sudo mkfs.ext4 /dev/vdc
Mount the volume to a new directory called /data:
>sudo mkdir /data
>sudo mount /dev/vdc /data
Check your new /data volume:
>df -h | grep vdc
You have now successfully attached and mounted your storage volume.
