Abhishek Kumar Singh

This document provides an overview of Linux-HA (High Availability) clustering. It discusses HA principles such as redundancy and eliminating single points of failure. It describes Linux-HA capabilities and components such as the Cluster Resource Manager. It also covers configuring resources and constraints in the Cluster Information Base (CIB) XML file.
