One command to make a filer path exportable over NFS: nfs.enable marks
the path with inode_index in filer.conf and backfills index rows for
the entries already under it, assigning inodes where missing, so
existing files resolve by filehandle right away. nfs.disable clears
the mark and deletes the rows, leaving no index data behind.
