This course is intended for
Senior Linux system administrators responsible for maximizing resiliency though high-availability clustering services and using fault-tolerant shared storage technologies.
Overview
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
This course will guide you through an 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 covers the same material as RH436, but includes the Red Hat Certified Specialist in High Availability Clustering exam (EX436). This course is based on Red Hat Enterprise Linux 7.1.
