2 Supported configuration
This section explains the supported configurations for NFS toolkit packages. The following are the
supported configurations:
• Failover of an NFS toolkit package from an NFS server node to an alternative node in a
cluster.
• Configuring two NFS toolkit packages using NFSv4 protocol.
• Coexistence of NFS toolkit package configured to use NFSv3 and NFSv4 package on the
same node.
Failover from an active NFS server node to an idle NFS server node
Figure 1 Failover from an active to idle NFS server node
Figure 1 (page 6) illustrates a failover from an active NFS server node to an alternative NFS
server node.
Node_A is the primary node for NFS server package Pkg_1. When Node_A fails, Node_B adopts
Pkg_1. In this case, Node_B locally mounts the file systems associated with Pkg_1 and export
directories mounted on a filesystem. Both Node_A and Node_B must have access to the disks that
holds the file systems for Pkg_1.
