264 is backup over NBD with reconnect. Here is another thing: check that the only small request works with reconnect, if disconnect occurs exactly after request was accepted by server and client knows, that requests is successfully accepted. We want to check that client will not wait reply forever but resend the request to new started NBD server. So, I think, they are different enough to keep them in separate. Still, if we want to merge them, it means that we should rewrite them in unittest style, with test-cases, as I think that huge text-camparing tests with several test cases are bad thing, I'll write a separate letter about it to discuss a bit later. -- Best regards, Vladimir
