Example Four - Two Servers with NFS

Cross-Mounts

This configuration has two servers and two packages. The primary node for each package NFS-mounts the file systems from its own package and the other package. Figure 3-7 illustrates this configuration. If one server fails, the other server adopts its package. The NFS mounts are not interrupted when a package fails over.
