To be able to recover from a disaster, you first have to understand and be able to recognize one. For the purpose of this chapter, we will work with the assumption that anything that leads to a sustained period of downtime is classed as a disaster. This will not cover scenarios where a failure happens that Ceph is actively working to recover from, or where it is believed that the cause is likely to be short lived. The other type of disaster is one that leads to a permanent loss of data unless recovery of the Ceph cluster is possible. Data loss is probably the most serious issue as the data may be irreplaceable or can cause serious harm to the future of the business.

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.
