Details:
The consumer of grub_util_raid_getmembers() expects a NULL terminated list of
device names. It has no idea about how many devices are registered in the
array; it only cares about active devices. As a result, there cannot be gaps
in the list, otherwise the first listed inactive device will cause all
remaining devices to effectively vanish. This is especially troublesome if a
root filesystem were on an array with the first device being a hot spare: the
array would appear to have no disks and the root filesystem would become
invisible to grub.
