You have to provide both EBS volume id and elastic ip as userdata separated by pipe symbol for this script to work. Add a name label to your volume to help avoid a mishap. An EBS volume can range from 1GB to 1TB and can be mounted to an Amazon EC2 instance as a device, each EBS volume can be mounted to one instance but multiple volumes can be mounted to the same instance. The reason you can't attach a volume to more than one instance is that EBS provides a "block storage" abstraction upon which customers run a filesystem like ext2/ext3/etc. EBS volumes are replicated within their availability zone and are durable if the EC2 instance to which they are attached should fail or terminate. See the Amazon EBS pricing.
