Design and deploy a high availability cluster

The intensive, hands-on Red Hat® High Availability Clustering (RH436) course teaches storage management, the Red Hat High Availability Add-On, and the shared storage technology delivered by Red Hat Global File System 2 (GFS2) and Red Hat Gluster Storage.

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 Certificate of Expertise in High Availability Clustering exam (EX436). This version of the course includes the exam.

Audience for this course

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

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
  • Configure GFS2 file systems

What is a Certificate of Expertise credential?

Red Hat Certificates of Expertise are specialized credentials available to individuals who pass performance-based exams. The certificates demonstrate skills and knowledge in specialized areas.

Impact on the organization

This course is intended to develop the skills needed to produce highly available, more resilient, mission critical applications, 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, students should 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 a high-availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems
  • Implement strategies to identify single points of failure in high-availability clusters, and eliminate them
