It's basically a per-mountpoint script that does NFS cleanups prior to allowing the file systems to be unmounted, and does sanity checks (makes sure nfsd is running prior to trying to call 'exportfs', for example). It's also a placeholder for future, um "special steps", that might need to happen as Linux NFS changes over time. It is designed to inherit everything it needs to know from the parent <fs> resource (and its parent service resource), which is why it can be reused. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
