I agree with Philip's assessment.

While this is very easy to reproduce in a VM (by just removing/adding
backing disk files), in practice and on real hardware, I think this is
definitely less likely.

When a real hardware disk fails, it should be removed from the system,
and not come back until it's replaced with new hardware, in which case
this bug will not be triggered. As Philip explained, this would only
happen if an admin is adding and removing and booting with just one
disk, and then the other, and then both. Don't do that.
