Hi! These empty files with sticky bit are so called link-files. Their extended attributes contains location of the server, where the real file resides. These link-files are used by distribute translator, when the actual location of a file differs from the location computed using name hash ( see lookup-unhashed option ). This could happen if GlusterFS installed over existing data or when number of servers changed.
