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 assume 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
Ceph is an open source distributed storage system that is scalable to Exabyte deployments. This second edition of Mastering Ceph takes you a step closer to becoming an expert on Ceph.
You’ll get started by understanding the design goals and planning steps that should be undertaken to ensure successful deployments. In the next sections, you’ll be guided through setting up and deploying the Ceph cluster with the help of orchestration tools. This will allow you to witness Ceph’s scalability, erasure coding (data protective) mechanism, and automated data backup features on multiple servers. You’ll then discover more about the key areas of Ceph including BlueStore, erasure coding and cache tiering with the help of examples. Next, you’ll also learn some of the ways to export Ceph into non-native environments and understand some of the pitfalls that you may encounter. The book features a section on tuning that will take you through the process of optimizing both Ceph and its supporting infrastructure. You’ll also learn to develop applications, which use Librados and distributed computations with shared object classes. Toward the concluding chapters, you’ll learn to troubleshoot issues and handle various scenarios where Ceph is not likely to recover on its own.
By the end of this book, you’ll be able to master storage management with Ceph and generate solutions for managing your infrastructure.
