J'ai ajouté 2 anciens disques durs de 2 To.
J'ai créé des partitions avec ce script pour mon raid :
#!/bin/bash
diskGB="$3"
sliceGB=1000
partsize=$(($sliceGB*1000*1000*1000/1024/1024 - 1))
for ((i=1; i <= $(($diskGB/$sliceGB)); i++))
do
sudo parted -a optimal -- "$1" mkpart md"$i"-"$2" $(($i+($i-1)*$partsize))MiB $(($i+$i*$partsize))MiB
done
sudo parted "$1" print freeMais même après un redémarrage, les partitions de l'un des disques durs n'apparaissaient pas. Il n'y a pas de /dev/sdb1 ou /dev/sdb2.
sudo gdisk /dev/sdb
