The examples in this section show how NFS instances can be configured on shared (or replicated) disks. Each diagram shows the relationship between the type of configuration and the NFS parameters. Each configuration also adheres to the configuration rules and requirements described in this section that ensure compatibility between the NFS configuration and the LifeKeeper software.
This section first describes the configuration requirements and then provides the configuration examples Active/Standby NFS v2/v3, Active/Active NFS v2/v3 and Active/Standby NFS v4.
The examples in this section are only a sample of the configurations than can be established, but understanding these configurations and adhering to the configuration rules will help define and set up workable solutions for your computing environment.
NFS Tag names are arbitrary names that describe protected file systems to LifeKeeper. The default tag name suggested by LifeKeeper is “nfs-<export point>.”
To understand the configuration examples, keep in mind that the underlying file system (or file systems if NFS v4 and bind mounts are used) must always be on shared or replicated disks. The file system(s) must be mountable from each of the paired systems.
