Сыпется жесткий?

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:

Забавный народ пошел, харду хана, так вместо того что бы останавливать и разбираться с железом мы «Перезагрузку пока не делал, боюсь все отвалится», еще напишите что надеетесь на «само рассосется».

Озвучьте, плиз, для статистики и любопытства ради модель жёсткого.

haku ★★★★★ ()

попробуй продиагностировать/забекапить что ещё читается с помощью sys-block/whdd

Немного офтопика. Забавно, у заказчика тоже ша сервак по дисковой системе навернулся, fs в readonly, сливаю полный архив по сети :) Но у меня проще там он виртуальный и с хост системой если че не мне разбираться. :)

В общем подготовил я систему на замену, основные сервисы восстановил. После перезагрузки проблемного сервера он загрузился без проблем. Все работает. В чем была проблема, какие логи смотреть? Что проверять?
