Montare hd raid1

situazione:
vecchio hd con partizioni raid (e dentro volumi logici) collegato via usb

1. da console come superuser scoprire la situazione con:
cat /proc/mdstat

2. disattivare tutti gli array (con gnome-disk-utility);

3. forzare mdadm ad attivare un array con un disco solo:
mdadm -A --verbose --run /dev/mdN /dev/sdLn

4. se sull'aray c'รจ un volume logico scoprirlo con:
pvs

5. identificarlo con:
lvdisplay

6. ed infine montarlo con:
mount

Nel caso specifico:
1.
[root@localhost ~]# cat /proc/mdstat

md125 : inactive sdd2[0](S)

md127 : inactive sdd1[1](S)

3.
[root@localhost ~]# mdadm -A --verbose --run /dev/md128 /dev/sdd1
