A Red Hat training course is available for Red Hat Ceph Storage

Chapter 1. Ceph Administration Overview

A Red Hat Ceph Storage cluster is the foundation for all Ceph deployments. After deploying a Red Hat Ceph Storage cluster, there are administrative operations for keeping a Red Hat Ceph Storage cluster healthy and performing optimally.

The Red Hat Ceph Storage Administration Guide helps storage administrators to perform such tasks as:

  • How do I check the health of my Red Hat Ceph Storage cluster?
  • How do I start and stop the Red Hat Ceph Storage cluster services?
  • How do I add or remove an OSD from a running Red Hat Ceph Storage cluster?
  • How do I manage user authentication and access controls to the objects stored in a Red Hat Ceph Storage cluster?
  • I want to understand how to use overrides with a Red Hat Ceph Storage cluster.
  • I want to monitor the performance of the Red Hat Ceph Storage cluster.

A basic Ceph Storage Cluster consist of two types of daemons:

  • A Ceph Object Storage Device (OSD) stores data as objects within placement groups assigned to the OSD
  • A Ceph Monitor maintains a master copy of the cluster map

A production system will have three or more Ceph Monitors for high availability and typically a minimum of 50 OSDs for acceptable load balancing, data re-balancing and data recovery.
