The story here is not how Silent Data Corruption is real. The story is that somebody did a bad home brew server build and fucked up.

So ZFS protects against end-user mistakes.

I was really hoping about a story on some large-scale study on silent data corruption, but no, just an ankedote.

Sad!

I didn't go into detail in the article, but the server in question is running a Supermicro X10SLH-F-O motherboard, ECC RAM, and a Haswell CPU, in a Rosewill RSV-L4411 4U chassis. Is there a hardware problem here? For sure. But you can't write this off as being some dusty overclock mess bought at someone's garage sale.

I have, incidentally, seen this in corporate environments on traditionally-engineered sever-class hardware as well. This is just a much more easily-discussed case.

What was the flaw in the setup that makes this not silent data corruption? That any other file system would not have caught the problem means corruption would have silently propagated to the application layer. And yet it didn't, because the corruption was detected. I fail to understand the point of this comment.
