Course Overview

Deploy reliable, available critical production services in a high availability cluster

In the Red Hat High Availability Clustering (RH436) course, you will learn how to provide highly available network services to a mission-critical enterprise environment through the deployment and management of shared storage and server clusters. Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities.

You will set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services such as web servers and databases on that cluster. Cluster storage components from the Resilient Storage Add-On are also covered; installations and applications that require multiple cluster nodes can access the same storage simultaneously. This includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

This package (course + exam) is based on Red Hat Enterprise Linux 8.3 and includes an exam voucher

Note:  Starting January 2026 this bundle (Course + Exam) only exists in CR (classroom) if scheduled or Closed course modalities.
If you are targeting a virtual class, please consider RH436LS the new RHLS-course subscription which includes as well an exam voucher

    • • Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
  • Accessing storage devices resiliently
    • • Configure resilient access to storage devices that have multiple access paths.
  • Configuring LVM in clusters
    • • Select, configure, and manage the correct LVM configuration for use in your cluster.
  • Providing storage with the GFS2 cluster file system
    • • Use the GFS2 cluster file system to simultaneously provide tightly coupled shared storage that can be accessed by multiple nodes.
  • Eliminating single points of failure
    • • Identify and eliminate single points of failure in your cluster to decrease risk and increase average service availability.

After this course participants should be able to:

  • • 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.
  • • Implement Logical Volume Manager (LVM) in cluster-aware configurations.
  • • Configure GFS2 file systems on storage shared by multiple nodes.

  • • RHCE certification or equivalent experience is expected
