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
- 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.
