No, the node number is part of the name of the TDB that is opened:

	/* open the database */
	ctdb_db->db_path = talloc_asprintf(ctdb_db, "%s/%s.%u",
					   ctdb_db_persistent(ctdb_db) ?
						ctdb->db_directory_persistent :
						ctdb->db_directory,
					   db_name, ctdb->pnn);

	tdb_flags = ctdb_db_tdb_flags(db_flags,
				      ctdb->valgrinding,
				      ctdb_config.tdb_mutexes);

again:
	ctdb_db->ltdb = tdb_wrap_open(ctdb_db, ctdb_db->db_path,
				      ctdb->tunable.database_hash_size, 
				      tdb_flags, 
				      O_CREAT|O_RDWR, mode);

There is no manipulation of the filename below this level.

Watching with interest...

peace & happiness,
