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 course is based on Red Hat Enterprise Linux 8.3.

Who Should Attend

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

Course Objectives

    • 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.

Course Outline

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.
