Figure 1-1 Simple Failover to an Idle NFS Server
Node_A is the primary node for NFS server package Pkg_1. When Node_A fails,
Node_B adopts Pkg_1. This means that Node_B locally mounts the file systems
associated with Pkg_1 and exports them. Both Node_A and Node_B must have access
to the disks that hold the file systems for Pkg_1.
Failover from One Active NFS Server to Another
Figure 1-2 shows a failover from one active NFS server node to another active NFS
server node.
