Сделал легкие смарт тесты хардов. Один из них умирает.
Боевая задача:
1) Подготовить машину к выключению для замены харда.
2) Включить машину, присоединить новый хард к рейду, синхронизировать.
Дано:
DDS, стоит у хостера.
Софтовый рейд 1.
Есть сетевое хранилище для бэкапов 100 Гб. Возможно расширить до 500 Гб. Больше - дорого.
На хостовой тачке Debian 6 + ProxMox
Несколько гостевых тачек.
Вводная инфа:
[console]smartctl -A /dev/sdb

Short тест sda ничего не показал, запустил расширенный. Жду.
Какой будет правильной последовательность действий в данном случае? Где что перепроверить? Загрузчик проверить, с рейдом что то сделать и т.д.
Нужно, чтобы машина после выключения смогла корректно запуститься.
Благодарен за дельные советы.
P.S.: Просьба в терминологию добавлять немного человеческого языка, я еще не достиг дзена в линуксе.
