Last active August 29, 2015 14:01

Basics for using Elastic Block Store (EBS) in your EC2-Instances (OS: Ubuntu)

	Mounting an EBS-Storage

	Variables:
	@device_name = /dev/sdf
	@device_mount = xvdf
	@mount_point = /my_space

	Select the EBS-Storage in the AWS-Console (Web-Interface) and attach it to the desired device.
	Here you can set the @device_name which is shown in your instance as @device_mount.
