Active/Active Configuration Example for NFS v2/v3

Configuration Notes:

  • The NFS software must be installed on both servers.

  • Initially, Server 1 exports /home/test and Server 2 exports /engdocs/app. In a switchover situation, one system can export both file systems.

  • File System A is the underlying file system for export point /home/test. File System B is the underlying file system for export point /engdocs/app.

  • The underlying file systems are on different shared disks.

Creating the First Resource Hierarchy on Server 1:

Server:

Server1

Export Point:

/home/test

IP Tag:

ip-172.17.100.202

NFS Tag:

nfs-/home/test

 

Extending the First Resource Hierarchy to Server 2:

Template Server:

Server1

Tag to Extend:

nfs-/home/test

Target Server:

Server2

Target Priority:

10

 

Creating the Second Resource Hierarchy on Server 2:

Server:

Server2

Export Point:

/engdocs/app

IP Tag:

ip-172.17.100.203

NFS Tag:

nfs-/engdocs/app

 

Extending the Second Resource Hierarchy to Server 1:
