I really, really, really hate unexplained problems like the one described here. Not in storage but any facet of computing. It's true that the systems we build and work on are complex, but they are also ultimately deterministic, and there is a reason why something goes wrong like TFA describes. Ideally we would seek to understand our systems before continuing to add features to them, but of course the real world often doesn't work that way.

This would be a super frustrating situation for me, particularly when you're not given the tools you need to diagnose in the first place, and you loop in support but they still can't help you identify what's wrong.

Years ago, I worked on a .NET system that sometimes would respond super slowly and we didn't have a concrete explanation for why. As in TFA, we developed a kind of religion about it. "Oh, it must be JITting", that sort of stuff.
