Создание RAID0 NVME
- fdisk /dev/nvme0n2 // p, 1, enter,etner
- fdisk /dev/nvme1n2 // p, 1, enter,etner
- nvme list
- fdisk -l
- partprobe
- df -h
- mdadm --create /dev/md3 -a yes -l 0 -n 2 /dev/nvme0n2p1 /dev/nvme1n2p1
- nvme list
- mkfs -t ext4 /dev/md3
- mount /dev/md3 /mnt
- df -h
Но лучше создать систему через rescue командой Installimage, там в блокноте вписать raid 0

1 Подключаемся через rescue чтобы освободить диски (ОС будет создавтаься с помощью дисков /dev/ram за счет ОЗУ и мы сможем настроить свободные NVME)
2 Удаляем диски на всякий
3 Проверяем
nvme list
fdisk --list
3 Создаем диски
и та же второй диск
4 проверяем
