Although we have seen the power that can be harnessed using Ceph's RADOS classes, it's important to note that this is achieved by calling your own customized code from deep inside OSDs. As a consequence, great care needs to be taken that your RADOS class is bug free. A RADOS class has the ability to modify any data on your Ceph cluster, and so accidental data corruption is easily possible. It is also possible for the RADOS class to crash the OSD process. If the class is used in large-scale cluster operations, this has the ability to affect all OSDs in the cluster, so great care should be taken to ensure that error handling is done properly to avoid errors.

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.
