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.

Deploying Ceph

Once you have planned your Ceph project and are ready to either deploy a test or production cluster, you will need to consider the method you wish to use to both deploy and maintain it. This chapter will demonstrate how to quickly deploy test environments for testing and development by the use of Vagrant. It will also explain the reasons why you might want to consider using an orchestration tool to deploy Ceph rather than using the supplied Ceph tools. As a popular orchestration tool, Ansible will be used to show how quickly and reliably a Ceph cluster can be deployed and the advantages that using it can bring.

In this chapter, you will learn about the following topics:

  • Preparing a testing environment with Vagrant and VirtualBox
  • Learning about the differences between ceph-deploy and orchestration tools
  • The advantages of using orchestration tools
  • Installing and using Ansible
  • Configuring the Ceph Ansible...
