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.
