- Para ver en que estado estoy podemos hacer un
cat /proc/mdstat
- clonar la tabla de particiones:
sfdisk -d /dev/sda | sfdisk /dev/sdb
- sincronizar el raid, haciendo esto para cada partición:
mdadm /dev/mdX -a /dev/sdbX
- cotillea un poco:
watch -n 1 cat /proc/mdstat
- grabar el grub con algo parecido a esto
grub --no-floppy find /boot/grub/stage1 device (hd0) /dev/sda root (hd0,0) setup (hd0) device (hd0) /dev/sdb root (hd0,0) setup (hd0)
- Que dara un resultado parecido a esto:
