I have the same setup for my router ... Openbsd 16-32gb if one dies I create a new one and set it up with ansible....

You are partly right. Zfs scrub is a repair tool when it has parity / mirrored copy of data to recreate it.

It's safe to make the assumption that the tool isn't magic.

A scrub can also repair data when using `ncopies` greater than one even outside any mirrors or parity.

Tbh guessing is part of the way to solve a bug. You need to make a hypothesis and the test if it is true. If not try another.

Saying the zfs/btrfs teams have no idea means the person has no idea about software development process ... It is a system none fully knows a system that complex.

If they did, the bug wouldn't have happened.

You have the ability to remove the stdlib if needed...

Recovered c++ dev here. I started with rust in 2016 and never looked back!!

I started in my own time and even back then it was superior...

People like c++ for the language features... I dislike it because of all the defensive programming one must do....
