Practical File System Design with the Be File System

вот дочитываю давеча subj - в главе про тестирование файловой системы автор жжет напалмом:
At this stage the testing group could still corrupt the file system, but it took a reasonable amount of effort (i.e.,more than15 minutes)
Before the first release of BFS, the system stabilized to the point where corrupting a hard disk took significant effort and all the real-world tests would run without corruption for 24 hours or more. At first customer ship, the file system had one known problem that we were unable to pinpoint but that would only happen in rare circumstances. By the second release (two months later) several more bugs were fixed, and the third release (another two months later) saw the file system able to withstand several days of serious abuse.
