привет!
вопрос мой про софтовый рейд и винты хитачи. есть /dev/md0, собраный из пяти одинаковых винтов Hitachi HDS723020BLA642 в raid5.
сегодня я проснулся с головной болью и^W^W^W^W открыл консоль после жалоб, что некоторые шары не работают и посмотрел /proc/mdstat, который радостно рапортовал, что sdb1 зафейлился.
вот смарт инфо всех пяти:

интересует, мог ли смарт ошибиться, и это просто проблемы в контакте, предположим, платы хдд с разъемом головок (тем, что под платой)? как видите, винты проработали более 9 тысяч часов без остановок в кондиционируемом помещении. что делать посоветуете? каковы шансы, что остальные винты пойдут по пути /dev/sdb?
спасибо!
