MC/ServiceGuard NFS for Linux is a separate set of shell scripts, and a
binary file that allow 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 like part of the client’s local file system.
With MC/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 MC/ServiceGuard starts the NFS package on the
adoptive node, the NFS file systems are re-exported from the adoptive
node with minimum disruption of service to users. The client side
“hangs” until the NFS server package comes up on the adoptive node.
When the service returns, the user can continue access to the file. You do
not need to restart the client.
The following version of the NFS Toolkit is now being made available:
