Part II Administrating Ceph on SUSE CaaS Platform Edit source

2 Rook-Ceph administration

This part of the guide focuses on routine tasks that you as an administrator need to take care of after the basic Ceph cluster has been deployed ("day two operations"). It also describes all the supported ways to access data stored in a Ceph cluster.

3 Block Storage

Block Storage allows a single pod to mount storage. This guide shows how to create a simple, multi-tier web application on Kubernetes using persistent volumes enabled by Rook.

4 CephFS

A shared file system can be mounted with read/write permission from multiple pods. This may be useful for applications which can be clustered using a shared file system.

5 Ceph cluster custom resource definitions

Rook allows the creation and customization of storage clusters through Custom Resource Definitions (CRDs). There are two different methods of cluster creation, depending on whether the storage on which to base the Ceph cluster can be dynamically provisioned.

6 Configuration

For almost any Ceph cluster, the user will want—and may need— to change some Ceph configurations. These changes often may be warranted in order to alter performance to meet SLAs, or to update default data resiliency settings.

7 Toolboxes

The Rook toolbox is a container with common tools used for rook debugging and testing. The toolbox is based on SUSE Linux Enterprise Server, so more tools of your choosing can be installed with zypper.

8 Ceph OSD management

Ceph Object Storage Daemons (OSDs) are the heart and soul of the Ceph storage platform. Each OSD manages a local device and together they provide the distributed storage. Rook will automate creation and management of OSDs to hide the complexity based on the desired state in the CephCluster CR as muc…

9 Ceph examples

Configuration for Rook and Ceph can be configured in multiple ways to provide block devices, shared file system volumes, or object storage in a Kubernetes namespace. We have provided several examples to simplify storage setup, but remember there are many tunables and you will need to decide what set…

10 Advanced configuration

These examples show how to perform advanced configuration tasks on your Rook storage cluster.

11 Object Storage

Object Storage exposes an S3 API to the storage cluster for applications to put and get data.

12 Ceph Dashboard

The Ceph Dashboard is a helpful tool to give you an overview of the status of your Ceph cluster, including overall health, status of the MOPN quorum, status of the MGR, OSD, and other Ceph daemons, view pools and PG status, show logs for the daemons, and more. Rook makes it simple to enable the dash…
