I updated an old box to -current/amd64 (6.99.40) about a fortnight ago, and noticed that its first root raid0 would fail with an IO error on shutdown. On startup, reconstructing it to itself seemed to work. I just thought the disk was old enough, and should get a new one.
Today, on an up-to-date -current/amd64 box (recent hardware, 6.99.42), I installed a brand new disk, to mirror from another reasonably new 2T existing disk. Same again: the new disk's first root raid0 partition fails with an IO error on shutdown and the component needs rebuilding. Coincidence? Cheers, Patrick
