Yes. I learned about this from this article

As this article pointed, raid6 has problem to support this. The patch which
I sent recent should fix this problem.
Interesting article.
In any case, RAID-6 offers a way to find this
type of unreported errors, albeit pro-actively.
"raid6check" implementents the considerations
of H. Peter Anvin in the paper:
https://mirrors.edge.kernel.org/pub/linux/kernel/people/hpa/raid6.pdf
Silent errors can be detected, in which drive,
if one only is present (per stripe).
