Chapter 1, Ceph - Introduction and Beyond, covers an introduction to Ceph, gradually moving toward RAID and its challenges, and a Ceph architectural overview. Finally, we will go through Ceph installation and configuration.
Chapter 2, Working with Ceph Block Device, covers an introduction to the Ceph Block Device and provisioning of the Ceph block device. We will also go through RBD snapshots and clones, as well as implementing a disaster-recovery solution with RBD mirroring.
Chapter 3, Working with Ceph and Openstack, covers configuring Openstack clients for use with Ceph, as well as storage options for OpenStack using cinder, glance, and nova.
Chapter 4, Working with Ceph Object Storage, covers a deep dive into Ceph object storage, including RGW setup and configuration, S3, and OpenStack Swift access. Finally, we will set up RGW with the Hadoop S3A plugin.
Chapter 5, Working with Ceph Object Storage Multi-Site V2, helps you to deep dive into the new Multi-site V2, while configuring two Ceph clusters to mirror objects between them in an object disaster recovery solution.
Chapter 6, Working with the Ceph Filesystem, covers an introduction to CephFS, deploying and accessing MDS and CephFS via kerenel, FUSE, and NFS-Ganesha.
Chapter 7, Monitoring Ceph Clusters, covers classic ways of monitoring Ceph via the Ceph command-line tools. You will also be introduced to Ceph Metrics and Grafana, and learn how to configure Ceph Metrics to monitor a Ceph cluster.
Chapter 8, Operating and Managing a Ceph Cluster, covers Ceph service management with systemd, and scaling up and scaling down a Ceph cluster. This chapter also includes failed disk replacement and upgrading Ceph infrastructures.
Chapter 9, Ceph under the Hood, explores the Ceph CRUSH map, understanding the internals of the CRUSH map and CRUSH tunables, followed by Ceph authentication and authorization. This chapter also covers dynamic cluster management and understanding Ceph PG. Finally, we create the specifics required for specific hardware.
Chapter 10, Production Planning and Performance Tuning for Ceph, covers the planning of cluster production deployment and HW and SW planning for Ceph. This chapter also includes Ceph recommendation and performance tuning. Finally, this chapter covers erasure coding and cache tuning.
Chapter 11, The Virtual Storage Manager for Ceph, speaks about Virtual Storage Manager (VSM), covering it’s introduction and architecture. We will also go through the deployment of VSM and then the creation of a Ceph cluster, using VSM to manage it.
Chapter 12, More on Ceph, covers Ceph benchmarking, Ceph troubleshooting using admin socket, API, and the ceph-objectstore tool. This chapter also covers the deployment of Ceph using Ansible and Ceph memory profiling. Furthermore, it covers health checking your Ceph cluster using Ceph Medic and the new experimental backend Ceph BlueStore.
Chapter 13, An Introduction to Troubleshooting Ceph, covers troubleshooting common issues seen in Ceph clusters detailing methods to troubleshoot each component. This chapter also covers what to look for to determine where an issue is in the cluster and what the possible cause could be.
Chapter 14, Upgrading Your Ceph Cluster from Hammer to Jewel, covers upgrading the core components in your Ceph cluster from the Hammer release to the Jewel release.
