Zusammenfassung:Application access to locally and remotely exported file systems is coordinated to allow caching data for exported file systems accessed by remote clients. In response to a request or file system access, it is determined whether the request relates to a locally exported file system or a remotely exported file system. If the request relates to a locally exported file system, a local access routine is invoked to obtain access permissions to the locally exported file system. If the request relates to remotely exported file system, a remote access routine is invoked to communicate with a local access routine in a file server responsible for coordinating access to the remotely exported file system to obtain access permissions to the remotely exported file system.
