Problem: ======== - During shutdown, InnoDB tries to free the asynchronous I/O slots and hangs. The reason is that InnoDB disables asynchronous I/O before waiting for pending asynchronous I/O to finish. buf_load(): InnoDB aborts the buffer pool load due to user requested shutdown and doesn't wait for the asynchronous read to get completed. This could lead to debug assertion in buf_flush_buffer_pool() during shutdown Fix: === os_aio_free(): Should wait all read_slots and write_slots to finish before disabling the aio. buf_load(): Should wait for pending read request to complete even though it was aborted. |
