Design and deploy a high availability cluster

The intensive, hands-on Red Hat® High Availability Clustering (RH436) course teaches storage management, the Red Hat High Availability Add-On, and the shared storage technology delivered by Red Hat Global File System 2 (GFS2) and Red Hat Gluster Storage.

Course Overview

Created for senior Linux® system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.

This course also helps you prepare for the Red Hat Certificate of Expertise in High Availability Clustering exam (EX436).

Content summary

  • Install and configure a Pacemaker-based high availability cluster
  • Create and manage highly available services
  • Troubleshoot common cluster issues
  • Work with shared storage (iSCSI) and configure multipathing
  • Configure GFS2 file systems

Audience and prerequisites

Audience for this course

  • Senior Linux system administrators responsible for maximizing resiliency though high-availability clustering services and using fault-tolerant shared storage technologies
