Configuring for a single NFS environment

Use this configuration to export all the local directories from a single virtual IP address. In this configuration, the NFS resource is part of a failover service group and there is only one NFS related service group in the entire clustered environment. This configuration supports lock recovery and also handles potential NFS ACK storms. This configuration also supports NFSv4. See Configuring for a single NFS environment.

Configuring for a multiple NFS environment

Use this configuration to export the NFS shares from a multiple virtual IP addresses. You need to create different NFS share service groups, where each service group has one virtual IP address. Note that NFS is now a part of a different parallel service group. This configuration supports lock recovery and also prevents potential NFS ACK storms. This configuration also supports NFSv4.

Configuring for multiple NFS environment with separate storage

Use this configuration to put all the storage resources into a separate service group. The storage resources such as Mount and DiskGroup are part of different service group. In this configuration, the NFS share service group depends on the storage service group. SFCFSHA uses this configuration where the service group containing the storage resources is a parallel service group. See Configuring NFS with separate storage.

Configuring NFS services in a parallel service group

Use this configuration when you want only the NFS service to run. If you want any of the functionality provided by the NFSRestart agent, do not use this configuration. This configuration has some disadvantages because it does not support NFS lock recovery and it does not prevent potential NFS ACK storms. Symantec does not recommend this configuration. See Configuring all NFS services in a parallel service group.
