Red Hat High Availability Clustering

Course code: RH436

Duration: 4 Days


Prerequisite:

If you want to take this course without the exam (RH436) and have not earned your RHCE® certification, you can confirm that you have the necessary knowledge by passing the online skills assessment.

Course Description:

Design and deploy a high availability cluster
Red Hat® High Availability Clustering (RH436) provides intensive, hands-on experience with the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, as well as cluster storage components from the Resilient Storage Add-On, including Cluster Logical Volume Manager (CLVM), Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

This course is based on Red Hat Enterprise Linux 7.1.

Created for senior Linux® system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.

This course also helps you prepare for the Red Hat Certified Specialist in High Availability Clustering exam (EX436).

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
•    Configure GFS2 file systems    

Intended Audience:

Senior Linux system administrators responsible for maximizing resiliency through high-availability clustering services and using fault-tolerant shared storage technologies

Course Outlines:

Clusters and storage
•    Get an overview of storage and cluster technologies.

Create high-availability clusters
•    Review and create the architecture of Pacemaker-based high-availability clusters.

Nodes and quorum
•    Review cluster node membership and how quorum is used to control clusters.

Fencing
•    Understand fencing and fencing configuration.

Resource groups
•    Create and configure simple resource groups to provide high-availability services to clients.

Troubleshoot high-availability clusters
•    Identify and troubleshoot cluster problems.

Complex resource groups
•    Control complex resource groups by using constraints.

Two-node clusters
•    Identify and work around two-node clusters issues.

ISCSI initiators
•    Manage iSCSI initiators for access to shared storage.

Multipath Storage
•    Configure redundant storage access.

Logical volume manager (LVM) clusters
•    Manage clustered LV.

Global File System 2
•    Create symmetric shared file systems.

Eliminate single points of failure
•    Eliminate single points of failure to increase service availability.

Comprehensive review
•    Set up high-availability services and storage.
