Abstract
A method for the stateless propagation of rename's between hierarchial file name spaces is provided. Under the method any standard rename command may be used on a filename located in a local file system name space (FSNS). Thereafter, when a file is renamed, that rename may be propagated through the use of three steps. First, when files have been renamed in either the local, remote or both FSNS, the filenames in the local FSNS must be matched with the corresponding file names in the remote FSNS. Then, after a match has been made, the current rename state is determined to see if the file was renamed in either, both or neither FSNS, or to see of the filename describes a new file not found in the other FSNS. Finally, after the name history for each file in both the local and remote FSNS's are updated, a propagation can occur which updates any changed file names in the remote FSNS, and also updates the entries in the remote FSNS name table and the local FSNS name table to reflect any such changes. In this way file name changes may be made without the need for a user to execute a special rename command.
