Vorbereiten
Starten Sie ihren dedizieren Server über das Webinterface in das Notfallsystem (Rescue).
Voraussetzungen
2 Festplatten
Notfallsystem (Rescue)
Partitionieren
Erstellen Sie nun die Partitionen auf der ersten Festplatte und kopieren Sie diese anschliessend auf die zweite Festplatte:
parted --script /dev/sda mklabel gpt mkpart primary 1MB 3MB name 1 grub set 1 bios_grub on mkpart primary 3MB 503MB name 2 boot set 2 boot on mkpart primary 503MB 100% name 3 system
sgdisk -R=/dev/sdb /dev/sda
The operation has completed successfully.
Nun können Sie das Software RAID erstellen:
mdadm --create /dev/md0 --level 0 --raid-devices=2 /dev/sda2 /dev/sdb2 --metadata=0.90
mdadm --create /dev/md1 --level 1 --raid-devices=2 /dev/sda3 /dev/sdb3
mdadm: array /dev/md0 started.
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md1 started.
pvcreate /dev/md1 -ffy
vgcreate lvm /dev/md1 -ffy
lvcreate -v -y -d -L 500MiB -n swap lvm
lvcreate -y -l 100%FREE -n root lvm -v

Formatieren Sie nun die Partitionen mit den einsprechenden Dateisystemen:
mkfs.ext4 -F -L boot /dev/md0
mkswap /dev/mapper/lvm-swap
swapon /dev/mapper/lvm-swap
mkfs.ext4 -F -L root /dev/mapper/lvm-root
mke2fs 1.44.5 (15-Dec-2018)
