Overview of this book

This Learning Path takes you through the basics of Ceph all the way to gaining in-depth understanding of its advanced features. You’ll gather skills to plan, deploy, and manage your Ceph cluster. After an introduction to the Ceph architecture and its core projects, you’ll be able to set up a Ceph cluster and learn how to monitor its health, improve its performance, and troubleshoot any issues. By following the step-by-step approach of this Learning Path, you’ll learn how Ceph integrates with OpenStack, Glance, Manila, Swift, and Cinder. With knowledge of federated architecture and CephFS, you’ll use Calamari and VSM to monitor the Ceph environment. In the upcoming chapters, you’ll study the key areas of Ceph, including BlueStore, erasure coding, and cache tiering. More specifically, you’ll discover what they can do for your storage system. In the concluding chapters, you will develop applications that use Librados and distributed computations with shared object classes, and see how Ceph and its supporting infrastructure can be optimized. By the end of this Learning Path, you'll have the practical knowledge of operating Ceph in a production environment. This Learning Path includes content from the following Packt products: • Ceph Cookbook by Michael Hackett, Vikhyat Umrao and Karan Singh • Mastering Ceph by Nick Fisk • Learning Ceph, Second Edition by Anthony D'Atri, Vaibhav Bhembre and Karan Singh

Exporting the Ceph Filesystem as NFS


The Network Filesystem (NFS) is one of the most popular shareable filesystem protocols that can be used with every Unix-based system. Unix-based clients that do not understand the Ceph FS type can still access the Ceph Filesystem using NFS. To do this, we would require an NFS server in place that can re-export Ceph FS as an NFS share. NFS-Ganesha is an NFS server that runs in user space and supports the Ceph FS File System Abstraction Layer (FSAL) using libcephfs.

In this recipe, we will demonstrate creating ceph-node1 as an NFS-Ganesha server and exporting Ceph FS as an NFS and mounting it on the client-node1.

How to do it...

Let's walk-through the steps to utilize client-node1 as an NFS-Ganesha server to export Ceph FS as NFS:

  1. On ceph-node1, install the packages required for nfs-ganesha:
        # sudo yum install -y nfs-utils nfs-ganesha
  1. Since this is a test setup, disable the firewall. For the production setup, you might consider enabling the required ports...
