Moví mi mdadm RAID5 a una placa base/procesador diferente, a la misma unidad de arranque.
La matriz ya no se encuentra durante un mdadm --assemble --scan
Anteriormente, la placa base ejecutaba INTEL RAID, por lo que cuando la inició mostró que las cuatro unidades del RAID5 no formaban parte del RAID.
