In this recipe, we will configure an additional server running Ubuntu 14.04 LTS to host the volumes, and we'll explore the prerequisites of Cinder-volume when it comes to attaching volumes to our instances.
To use Cinder volumes, you will need to have an additional host running Ubuntu 14.04 LTS. This host will be configured to provide a loopback filesystem on which we will build the LVM volumes and install the required services for Cinder.
If you are using the Vagrant environment that accompanies this book, be sure to login to the cinder node with the following commands:
vagrant up cinder vagrant ssh cinder
The terms OpenStack Block Storage and Cinder will be used interchangeably in this chapter.
