Red Hat® High Availability Clustering (RH436) provides intensive, hands-on experience in deploying and managing shared storage and server clusters.

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 course is based on Red Hat Enterprise Linux 8.3.

Skills Covered

  • 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.

Prerequisites

Target Audience

  • Senior Linux system administrators who use high-availability clustering and fault-tolerant shared storage technologies to maximize resiliency of production services.
