Всем доброго дня! На сервере стоит Centos 6. Пару дней назад пропал /dev/sda. На серваке вроде как должно стоять зеркало из 2х ЖД, но фактически хз, не проверял, руки еще не дошли.Судя по логам отвалился жесткий и сыпятся кластеры? Перезагрузку пока не делал, боюсь все отвалится))) Можно ли в таком состоянии сделать рабочий образ или бекап?
Так вот вывод dmesg:
