Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

Deploying Ceph using Ansible


In this book, we have discussed deploying Ceph in multiple ways, which includes using Ceph-deploy and the Virtual Storage Manager (VSM). Both of these methods require the manual installation and configuration of the Ceph cluster. However, there exist other tools and methods that can install and deploy Ceph for you in a highly automated fashion. With such tools, you no longer need to type boring commands to deploy Ceph; configuration management tools such as Ansible, Puppet, and Chef, among others, can install and configure the Ceph cluster as you like.

Getting ready

In this recipe, we will go through Ansible, which is a very simple IT automation and configuration management tool; for more information on Ansible, take a look at http://www.ansible.com/how-ansible-works. The Ceph ecosystem has a vibrant community around it that has developed ready-to-use Ansible modules for Ceph. We will be using these ceph-ansible modules (refer to https://github.com/ceph/ceph-ansible...
