NAS542 con 4 discos RAID1, no me deja pasarlo a RAID5.

Cuando voy al volumen no me deja Administrar el volumen

I'm afraid the conversion from raid1 to raid5 doesn't exist. At least not with the mdadm on the box. As a test I created a 4 disk raid1 array from 4 loop devices on my NAS520, and tried to convert that to raid5.
