Что-то случилось с моим бесперебойником и он отключился. После отключения один из дисков длительно проверялся и сыпал ошибками.
Сейчас его SMART такой:
> sudo smartctl -a /dev/sdb

Дополнительный вопрос - как узнать какие файлы в поврежденных секторах? Очень не хочется тянуть весь бэкап.
Ну и на последок вопрос - что купить на замену? Это файлохранилище, как наверно понятно их имен точек монтирования. Фоточки, кинцо, музыка. Скорость особенно не нужна соответственно. Надежность и тишина в приоритете.
