Overview of this book

Ceph is a unified distributed storage system designed for reliability and scalability. This technology has been transforming the software-defined storage industry and is evolving rapidly as a leader with its wide range of support for popular cloud platforms such as OpenStack, and CloudStack, and also for virtualized platforms. Ceph is backed by Red Hat and has been developed by community of developers which has gained immense traction in recent years. This book will guide you right from the basics of Ceph , such as creating blocks, object storage, and filesystem access, to advanced concepts such as cloud integration solutions. The book will also cover practical and easy to implement recipes on CephFS, RGW, and RBD with respect to the major stable release of Ceph Jewel. Towards the end of the book, recipes based on troubleshooting and best practices will help you get to grips with managing Ceph storage in a production environment. By the end of this book, you will have practical, hands-on experience of using Ceph efficiently for your storage requirements.

Accessing Ceph FS through kernel driver

Native support for Ceph has been added in the Linux kernel 2.6.34 and the later versions. In this recipe, we will demonstrate how to access Ceph FS through the Linux kernel driver on client-node1.

How to do it...

In order for our client to have access to Ceph FS, we need to configure the client for accessing the cluster and mounting Ceph FS. Let's review how this is done:

  1. Check your client's Linux kernel version:
        root@client-node1 # uname -r
  1. Create a mount point directory in which you want to mount the filesystem:
        # mkdir /mnt/cephfs
  1. Get the keys for the client.cephfs user, which we created in the last section. Execute the following command from the Ceph...
