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

Accessing Ceph FS through FUSE client


The Ceph Filesystem is natively supported by the LINUX kernel; however, if your host is running on a lower kernel version or if you have any application dependency, you can always use the FUSE client for Ceph to mount Ceph FS.

How to do it...

Let's review how to configure FUSE client for access to the Ceph cluster and mounting Ceph FS:

  1. Validate that the Ceph FUSE package is installed on the machine client-node1 (Ansible installs this as part of the client packages):
        # rpm -qa |grep -i ceph-fuse
  1. Validate that the Ceph FS keyring file is created client-node1 in /etc/ceph/ceph.client.cephfs.keyring, with the following contents (note your key will be different from the example):
  1. Mount Ceph FS using the FUSE client:
        # ceph-fuse --keyring /etc/ceph/ceph.client.cephfs.keyring 
                    --name client.cephfs -m ceph-node1:6789 /mnt/cephfs
  1. To mount Ceph FS at OS boot, add the following lines to the /etc/fstab file on the client-node1:
     ...
