About this course

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


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.


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.


1 - Creating high availability clusters
  • Create a basic high availability cluster.
2 - Managing cluster nodes and quorum
  • Manage node membership in the cluster and describe how it impacts cluster operation.
3 - Isolating malfunctioning cluster nodes
  • Isolate unresponsive cluster nodes to protect data and recover services and resources after a failure.
4 - Creating and configuring resources
  • Create basic resources and resource groups to provide highly available services.
5 - Troubleshooting high availability clusters
  • Identify, diagnose, and fix cluster issues.
6 - Automating cluster and resource deployment
  • Deploy a new high availability cluster and cluster resources using Ansible automation.
7 - Managing two-node clusters
  • Operate two-node clusters while identifying and avoiding issues specific to a two-node cluster configuration.
8 - Accessing iSCSI storage
  • Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
9 - Accessing storage devices resiliently
  • Configure resilient access to storage devices that have multiple access paths.
10 - Configuring LVM in clusters
  • Select, configure, and manage the correct LVM configuration for use in your cluster.
11 - Providing storage with the GFS2 cluster file system
  • Use the GFS2 cluster file system to simultaneously pProvide tightly coupled shared storage that can be accessed by multiple nodes.
12 - Eliminating single points of failure
  • Identify and eliminate single points of failure in your cluster to decrease risk and increase average service availability.
  • Note: Course outline is subject to change with technology advances and as the nature of the underlying job evolves. For questions or confirmation on a specific objective or topic, please contact a training specialist.
