About Clustered NFS

In previous releases, the SFCFS stack only allowed an active/passive setup for

NFS serving due to the complexity of lock reclamation in an active/active

configuration. This new Clustered NFS (CNFS) feature gracefully handles failure

of any node and reclaim the locks in such a way as to not accidentally lose any

existing lock grants without notification.

This release only supports NFS Version 3.

See “How to mount an NFS-exported file system on the NFS clients” on page 158.

Requirements

■ Prior knowledge of NFS is a prerequisite.
