Active - Standby - NFS v2-v3

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.

Note: In an active/standby configuration, Server 2 might be running NFS but does not have any other NFS resources under LifeKeeper protection.

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:
