-------------------------------------------------------------------     Welcome to the Hetzner Rescue System.     This Rescue System is based on Debian 10 (buster) with a custom   kernel. You can install software as in a normal system.     To install a new operating system from one of our prebuilt   images, run 'installimage' and follow the instructions.     More information at http://wiki.hetzner.de   -------------------------------------------------------------------   Rescue System up since 2020-06-23 19:15 +02:00   Hardware data:      CPU1: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (Cores 8)    Memory:  32035 MB    Disk /dev/sda: 3000 GB (=> 2794 GiB) doesn't contain a valid partition table    Disk /dev/sdb: 3000 GB (=> 2794 GiB) doesn't contain a valid partition table    Total capacity 5589 GiB with 2 Disks   Network data:    eth0  LINK: yes          MAC:  51:41:5d:9f:61:f3          IP:   51.91.111.128          IPv6: 2a11:4f81:1612:3333::3/64          RealTek RTL-8169 Gigabit Ethernet driver

El servidor tiene 2 HDD (3000 GB), ahora queremos usar una unidad con capacidad alrededor de 6000 GB, usamos RAID-0

Paso 1: use el comando:

1	installimage

Paso 2: Elija CentOS y luego ingrese o haga clic en Aceptar

Paso 3: Elija CentOS-78-64-minimal y luego ingrese o haga clic en Aceptar

Paso 4: ingrese o haga clic en Aceptar

Ahora veremos un editor, podemos editar la configuración del archivo:

Paso 5:
editamos algunas líneas:

1	SWRAIDLEVEL 1

a

1	SWRAIDLEVEL 0

1 2 3 4

PART swap swap 16G PART /boot ext3 512M PART / ext4 1024G PART /home ext4 all

a

1 2 3

PART swap swap 16G PART /boot ext3 512M PART / ext4 all

Luego presione F2 para guardar y F10 para salir del editor

Elija Sí (repita 2 veces)

Listo, ahora espera unos 3 minutos
