Without fsync, there's no guarantee that anything you wrote was written. The OS delays the writes. If you close, the data is still in memory, the OS later tries to write and fails with an IO error, and it has no way to tell you about the problem, and discards the pages. If you read it back, it might be garbage, truncated, or something else, and no IO error was ever reported, let alone a system crash. -- This is an automated message from the Apache Git Service.
