Red Hat High Availability Clustering With Exam (RH437)
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.
Course Objectives
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
Agenda
- Get an overview of storage and cluster technologies.
- Review and create the architecture of Pacemaker-based high-availability clusters.
- Review cluster node membership and how quorum is used to control clusters.
- Understand fencing and fencing configuration.
- Create and configure simple resource groups to provide high-availability services to clients.
- Identify and troubleshoot cluster problems.
- Control complex resource groups by using constraints.
- Identify and work around two-node clusters issues.
- Manage iSCSI initiators for access to shared storage.
- Configure redundant storage access.
- Manage clustered LVM.
- Create symmetric shared file systems.
- Eliminate single points of failure to increase service availability.
