Софтовый рейд. Замена диска Debian 6, pve

 , ,


0

1

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.
