Managing Serviceguard NFS for Linux, July 2007

Sample Configurations
Chapter 3 41
3 Sample Configurations
This chapter gives sample cluster configuration files, package
configuration files, package control script, and NFS control script for
configurations supporting the following failover options:
• Failover between multiple active nodes. The sample configuration
has three servers and three Serviceguard NFS packages and
supports a three-server mutual takeover. Each server is the primary
node for one package and an adoptive node for the other two
packages.
• One adoptive node for two packages. The sample configuration has
two packages, each owned by a different server. A third server is the
adoptive node for both packages. This sample configuration uses the
package control option, which prevents the adoptive node from
adopting more than one package at a time.
• Multiple node cascading failover. The sample configuration has three
servers and two packages. One server is the primary node for both
packages, and the other two servers are adoptive nodes for both
packages.
• One adoptive node for an NFS package with File Lock Migration.
The sample configuration has two servers and one Serviceguard NFS
package. One server is the primary node and the other server is the
adoptive node for the NFS package. This sample configuration
enables the File Lock Migration Feature.
NOTE Examples in this chapter are RedHat specific.
The sample configuration files in this chapter show only the configured
values. Most of the comments have been omitted.
