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.

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


Impact on the organization

High availability clustering can improve reliability, availability, and resiliency of your mission-critical services, resulting in reduced downtime and easier hardware maintenance.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

Impact on the individual

As a result of attending this course, you will be able to create, manage, and troubleshoot highly available network services and tightly-coupled cluster storage for business-critical applications.

Students should be able to demonstrate the following skills:

  • Improve application uptime by using high availability clustering.
  • Manage storage in an high availability environment using iSCSI initiators, HA-LVM or LVM Shared Volume Groups as appropriate, and GFS2 cluster file systems.
  • Implement strategies to identify and eliminate single points of failure in high availability clusters.

Grupa docelowa:

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

  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 provide 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.
