	Before Failover:

Node_A

Node_B

Pkg_1

disks

After Failover:

Node_A

Pkg_1 disks

Node_B

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.
