Configuring two NFS toolkit packages using NFSv4 protocol
Figure 2 Configuring two NFSv4 toolkit packages
Figure 2 (page 7) shows a scenario where two NFS toolkit packages are using NFSv4 protocol.
This configuration supports two NFSv4 packages. In this configuration, Node_A is the primary
node for NFS server packages, Pkg1_v4 and NFS server package Pkg2_v4, which is configured
to use NFSv4 protocol.
When Node_A fails, Node_B adopts both Pkg1_v4 and Pkg2_v4, which are configured to use
NFSv4 protocol and exports the file systems in NFSv4 way of exporting. When two or more
packages are configured to use NFSv4 protocol in the same system, then you must use single
virtual root directory provided for those packages. So, NFSv4_VIRTUAL_ROOT parameter must
be same for all NFS toolkit packages if they are configured to use NFSv4 protocol on the same
system.
NOTE: If you use multiple virtual root directories for a single system, then it might lead to an
unexpected behavior.
