mdadm build игнорируя --force? Raid10 минимальная разница в «действиях» между жесткими дисками

На моем сервере запущен 4-х дисковый программный код raID 10 на основе mdadm.

EarlIer Сегодня небольшое отключение электроэнергии отключило сервер, и теперь он загружается только в аварийную систему InItrd (ubuntu 16.04), при этом около двух из четырех сообщений «возможно устарели». Между четырьмя окнами есть небольшая разница в событиях. Два из них имеют 6531 событие, два 6527 событий.

Я попытался заново собрать рейд силой:

mdadm --assemble /dev/md0 /dev/sdb /dev/sdc /dev/sdd /dev/sde --force -v

А также без силы:

mdadm --assemble /dev/md0 /dev/sdb /dev/sdc /dev/sdd /dev/sde -v

Он продолжает уговаривать устаревшие механизмы.

Как я мог получить mdadm, чтобы игнорировать небольшое различие в событиях?

Вот результаты:
