An example of Active/Active consists of two or more systems actively running NFS and exporting file systems.

Active/Active Configuration Example

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:

Template Server: Server2
Tag to Extend: nfs-/engdocs/app
Target Server: Server1
Target Priority: 10
