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.
