Why does this always come up in the last minute? :-( The real fix shouldn't be in the devices, but blk_aio_*() needs to handle empty drives gracefully. We already made a similar fix before the last release in commit 4da97120d, and I already didn't like it back then. Of course, we should have used the time to fix this properly, but as you can see, nothing has happened and we're running out of time again. Kevin
