Я пытаюсь использовать мой программный рейд после переустановки CentOS 7. Я не могу запустить мой RAID-5. Если я запускаю CentOS-Gnome Live DVD (1708), файловый менеджер показывает мой raid-диск, монтирует его и я могу получить доступ ко всем данным. Я думаю, что мне не хватает чего-то действительно простого. Может ли кто-нибудь заметить мою ошибку?
RAID-5 состоит из 4 устройств:
- / DEV / sdb1
- / DEV / sdc1
- / DEV / sdd1
- / DEV / sde1
Выходы:
