Introduction
This FAQ answers questions about the cluster project as a whole, broken into its components. Some of the answers cross multiple components, so if you don't see the question you're looking for, search the wiki and you may find the question and answer under a different component. In many cases, there are multiple answers to every question. For example, there's the answer that a developer wants to hear, and there's the answer that a lay person wants to hear without the technical jibberish. In most cases I've tried to provide answers suitable to lay people and people who are relatively new to clustering technology.
If you have corrections or additional questions not addressed here, please mail them to to linux-cluster@redhat.com
