Overview of this book

Ceph is a unified distributed storage system designed for reliability and scalability. This technology has been transforming the software-defined storage industry and is evolving rapidly as a leader with its wide range of support for popular cloud platforms such as OpenStack, and CloudStack, and also for virtualized platforms. Ceph is backed by Red Hat and has been developed by community of developers which has gained immense traction in recent years. This book will guide you right from the basics of Ceph , such as creating blocks, object storage, and filesystem access, to advanced concepts such as cloud integration solutions. The book will also cover practical and easy to implement recipes on CephFS, RGW, and RBD with respect to the major stable release of Ceph Jewel. Towards the end of the book, recipes based on troubleshooting and best practices will help you get to grips with managing Ceph storage in a production environment. By the end of this book, you will have practical, hands-on experience of using Ceph efficiently for your storage requirements.

Configuring Cinder for Ceph backend

The Cinder program of OpenStack provides block storage to virtual machines. In this recipe, we will configure OpenStack Cinder to use Ceph as a storage backend. OpenStack Cinder requires a driver to interact with the Ceph Block Device. On the OpenStack node, edit the /etc/cinder/cinder.conf configuration file by adding the code snippet given in the following section.

How to do it...

In the last recipe, we learned to configure Glance to use Ceph. In this recipe, we will learn to use the Ceph RBD with the Cinder service of OpenStack:

  1. Since in this demonstration we are not using multiple backend cinder configurations, comment the enabled_backends option from the /etc/cinder/cinder.conf file...
