Prerequisite Configuration - Red Hat ENTERPRISE LINUX 5 - CONFIGURATION NFS OVER GFS Configuration Manual

Chapter 2.

Prerequisite Configuration

This document describes a procedure for configuring cluster resources and a cluster service. Before
beginning this procedure, you must configure a cluster with a fencing device configured for each node
in the cluster. In addition, you must configure a logical volume with a GFS filesystem that can be
shared among the nodes in the cluster.
Table 2.1, "Configuration Prerequisities"
have been set up before this procedure beings.

Table 2.1. Configuration Prerequisities
No failover domain has been defined for this cluster. The cluster software determines on which node
to run the NFS service.
For information on configuring a cluster, see Configuring and Managing a Red Hat Cluster. For
information on configuring an LVM volume, see LVM Administrator's Guide: Configuration and
Administration.
