Assuming FSM is referring to defects, witnessing no defects increases confidence that no defects exist in the observed state.
Conversely, witnessing defects does not itself prove defects exist if the test cases were not scientific, it increases the confidence that defects exist but there exists some probability that an unrelated defect (bad ram, kernel error, hardware failure, solar flares) could have caused the issue.
But there’s also a lot of evidence to suggest Brtfs has had a lot of defects resolved in recent years, so it’s also important to note that as time moves forward, the amount of existing and likely rate of introducing new defects is likely to decrease.
I should add ive had minimal skin in this game until yesterday. I chose brtfs for two systems for snapshot support, but that’s in addition to regular backups on another host, because it’s silly to trust any single compute node regardless of file system.
No. It is referring to the Flying Spaghetti Monster, but is an analogy for anything including defects. This is discussion about epistemology not filesystems.
