in buf_dblwr_t::init_or_load_pages() - InnoDB fails to set the TRX_SYS_DOUBLEWRITE_SPACE_ID_STORED flag in transaction system header page while recreating the undo log tablespaces buf_dblwr_t::init_or_load_pages(): Tries to reset the space id and try to write into doublewrite buffer even when read_only mode is enabled. In srv_all_undo_tablespaces_open(), InnoDB should try to open the extra unused undo tablespaces instead of trying to creating it.
