$ mount -t proc /proc /mnt/proc/
$ mount -t sysfs /sys /mnt/sys/
$ mount -o bind /dev /mnt/dev/
$ chroot /mnt /bin/bash
$ export HOME=/root
$ export http_proxy=http://proxy.fcen.uba.ar:8080

Como el sistema lo estamos instalando sobre un RAID, lo que necesitamos es el paquete mdadm

$ apt install mdadm

Como estamos instalando el paquete mdadm automáticamente actualiza el archivo /etc/mdadm/mdadm.conf por eso no ejecutamos

$ mdadm --detail --scan | tee -a /etc/mdadm/mdadm.conf

Ahora tenemos que modificar el archivo /etc/fstab

$ echo “/dev/md3 / ext4 defaults,nofail,discard 0 0” | tee -a /etc/fstab
