отвалился программный RAID-0

[конь]

Ubuntu server 14.04. 1HDD - 500ГБ под систему и 4HDD по 2ТБ в программном нулевом рейде. до сегодняшнего дня все работало нормаль. Сегодня увидел что RAID пропал. есть какая нить возможность его вернуть удаленно? информация не важна.

DeviceDisappeared event detected on md device /dev/md/0

это не есть хорошо... Возможно, у Вас проблемы с каким-то диском - нужно смотреть S.M.A.R.T. всех четырех дисков из рейда.

[AnrDaemon]

У Вас RAID собран на контроллере.
Удалённо, боюсь, никак. Возможно, слетели настройки BIOS.

[конь]

рейд был собран через установщик Ubuntu. Через Викторию проверил диски, 1 оказался мертвый. собрал из трех. опять работает. всем спс

[hohlov.jurii]

Скиньте ссылочку на программу Викторию.

[AnrDaemon]

Вас в гугле или в яндексе забанили?
