Abstract
A system and method for migrating file systems is provided. A file system migration operation copies a plurality of files from a first file system to a second file system. A request to access one of the files being migrated during the file system migration operation results in the creation of a pseudo vnode for the file being requested in the second file system. The pseudo vnode is created prior to creating a vnode for the file in the second file system. In addition, the pseudo vnode is associated with a vnode of the file at the first file system. Information identifying the pseudo vnode is then returned to the application.
