Ceph Administration and Troubleshooting Course Details:

The Ceph Storage Administration course provides a hands on approach to understanding one of the most popular storage system solutions.  Ceph is a free-software storage platform that implements object storage on a single distributed computer cluster, and provides interfaces for object-, block- and file-level storage.  This course teaches storage basics and then moves into the architecture of Ceph, administration and the analysis of the Ceph components in a production environment. This is a lab intensive 5-day course.

    No classes are currenty scheduled for this course.

  5. Additional kubernetes and helm considerations
    • Install and start helm
    • Add ceph-helm to helm local repos
    • Configure your ceph cluster
    • Configure rbac permissions
    • Label kubelets
    • Ceph deployment
    • Configure a pod to use a persistent volume from ceph
    • Logging

  6. Troubleshooting common problems
    • Measuring performance
    • Log analysis
    • Perform troubleshooting lab exercises that will test the students knowledge of architecture, logging, and administration by solving problems. (RBD only troubleshooting examples for this class)

*Please Note: Course Outline is subject to change without notice. Exact course outline will be provided at time of registration.

Students will learn how to install and manage a Ceph cluster, utilize a CRUSH map, storage pools, mirroring and snapshots.  As well, students learn to monitor a cluster using common Ceph tools.  Additionally, students will deploy kubernetes on Ceph while troubleshooting their environments.

Basic Linux skills are helpful but not mandatory

Familiarity with a text editor like vi, vim, or nano is helpful.

Any company or individual who wants to advance their knowledge of the cloud environment, keep up with the most recent changes, and prepare themselves for the future of applications and services in the public or private cloud environment. Networking, general IT, devOps, systems, and storage folks would be a great fit.
