    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.
