Mechanism to re-export NFS client mount points from nodes in a cluster

摘要

Mechanism for re-exporting Network File System (NFS) mount points. In one embodiment, a first server may send a file handle lookup request for a file in a file system to a second server that imported the file system from a third server and re-exported the file system to the second server. The second server may access a file handle mapping mechanism to generate a file handle for the file on the second server. The first server may send an I/O request including the file handle to the second server. The second server may access the file handle mapping mechanism to generate a file handle for the file on the third server from the file handle received in the I/O request. The second server forwards the I/O request to the third server using the new file handle. Results of the request are forwarded to the first server by the second server.
