This section provides an example of Active/Standby for NFS v2/v3. In this configuration, Server 1 is considered active because it is running NFS and exporting the file system. Server 2 does other processing. If Server 1 fails, Server 2 gains access to the file system and uses the LifeKeeper secondary hierarchy to make it available to clients.

Active/Standby Configuration Example for NFS v2/v3

Configuration Notes:

  • The NFS software must be installed on both servers.
  • The underlying file system (File System A) must be on a shared (or replicated) disk.
  • The NFS export point is /home/test.
  • The exported file system must have the same mount point on both the primary and backup servers.
  • Server 2 cannot access files and directories on the shared disk while Server 1 is active.

Creating a Resource Hierarchy to Server 1:

Server: Server1
Export Point: /home/test
IP Tag: ip-172.17.100.202
NFS Tag: nfs-/home/test

Extending a Resource Hierarchy to Server 2:

Template Server: Server1
Tag to Extend: nfs-/home/test
Target Server: Server2
Target Priority: 10
