Add EBS volume to a Linux EC2 Instance

  1. Create an EBS volume using the AWS console (WEB UI)
  2. Using the AWS console, attach the EBS volume to running instance. The attached volume may get assigned to /dev/sdf (EC2’s external name for this particular device number).
  3. Format file system /dev/xvdf (Ubuntu’s internal name for this particular device number):
    sudo mkfs.ext4 /dev/xvdf
    
  4. Mount file system (with update to /etc/fstab so it stays mounted on reboot):
    sudo mkdir -m 000 /vol
    echo "/dev/xvdf /vol auto noatime 0 0" | sudo tee -a /etc/fstab
    sudo mount /vol
