Mastering Ceph

By: Nick Fisk

Overview of this book

Mastering Ceph covers all that you need to know to use Ceph effectively. Starting with design goals and planning steps that should be undertaken to ensure successful deployments, you will be guided through to setting up and deploying the Ceph cluster, with the help of orchestration tools. Key areas of Ceph including Bluestore, Erasure coding and cache tiering will be covered with help of examples. Development of applications which use Librados and Distributed computations with shared object classes are also covered. A section on tuning will take you through the process of optimisizing both Ceph and its supporting infrastructure. Finally, you will learn to troubleshoot issues and handle various scenarios where Ceph is likely not to recover on its own. By the end of the book, you will be able to successfully deploy and operate a resilient high performance Ceph cluster.

One solution to making the installation and management of Ceph easier is to use an orchestration tool. There are several tools available, such as Puppet, Chef, Salt, and Ansible, all of which have Ceph modules available. If you are already using an orchestration tool in your environment, then it would be recommended that you stick to using that tool. For the purposes of this book, Ansible will be used; this is for a number of reasons:

  • It's the favored deployment method of Red Hat, who are the owners of both the Ceph and Ansible projects
  • It has a well-developed and mature set of Ceph roles and playbooks
  • Ansible tends to be easier to learn if you have never used an orchestration tool before
  • It doesn't require a central server to be set up, which means demonstrations are more focused on using the tool rather than installing it

All tools follow the same principle of where you provide them with...
