Serviceguard NFS Toolkit for Linux Version A.03.00 Release Notes, March 2009

1 Serviceguard NFS for Linux Version A.03.00 Release
Notes
Announcements
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:
• Product T1442 — version A.03.00 — software and license
Serviceguard NFS for Linux is being released for use with the Linux operating system running
