This section provides an example of Active/Standby for NFS v4. In this configuration, Server 1 is considered active because it is running NFS and exporting the file systems. Server 2 does other processing. If Server 1 fails, Server 2 gains access to the file systems and uses the LifeKeeper secondary hierarchy to make it available to clients.
Active/Standby Configuration Example for NFS v4
- The NFS software must be installed on both servers.
- The underlying file systems (File Systems A, B and C) must be mounted and be on shared (or replicated) disks.
- Bind mounts must be completed prior to creation (bind /usr/local/bin to /export/bin and bind /usr/local/opt to /export/opt).
- The NFS export points are /export, /export/bin and /export/opt.
- The exported file systems 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.
