Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

Ceph recommendation and performance tuning


In this recipe, we will learn some performance tuning parameters for the Ceph cluster. These cluster-wide configuration parameters are defined in the Ceph configuration file so that each time any Ceph daemon starts, it will respect the defined settings. By default, the configuration file name is ceph.conf, which is located in the /etc/ceph directory. This configuration file has a global section as well as several sections for each service type. Whenever a Ceph service type starts, it applies the configuration defined under the [global] section as well as the daemon specific section. A Ceph configuration file has multiple sections, as shown in the following screenshot:

We will now discuss the role of each section of the configuration file.

  • Global section: The global section of the cluster configuration file begins with the [global] keyword. All the settings defined under this section apply to all the daemons of the Ceph cluster. The following is an...
