Build and manage highly available Red Hat Enterprise Linux clusters for mission-critical workloads.

The training teaches senior Linux system administrators how to deploy, configure, and manage high availability (HA) clusters using Pacemaker and shared storage technologies.
Through intensive, hands-on labs, you’ll gain the practical skills to ensure your applications remain reliable, fault-tolerant, and continuously available, even in case of system or hardware failure.

Participants will configure clustered storage components from the Resilient Storage Add-On, allowing multiple cluster nodes to simultaneously access shared data through 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.
