Serviceguard NFS for Linux consists of a separate set of shell scripts and
a binary file, which allows you to configure Serviceguard packages that
mount highly available networked file systems.
An NFS server is a host that “exports” its local directories (makes them
available for client hosts to mount using NFS). On the NFS client, these
mounted directories look to users as part of the client’s local file system.
With Serviceguard NFS, the NFS server package containing the
exported file systems can move to a different node in the cluster in the
event of failure. After Serviceguard starts the NFS package on the
adoptive node, the NFS file systems are re-exported from the adoptive
node with a minimum disruption of service. The client side “hangs” until
the NFS server package comes up on the adoptive node. When the
service returns, you can continue access to the file without the need to
restart the client.
The following version of the NFS Toolkit is now being made available:
