You are right. But in my case groot and root are the same, because I
don't have a separate partition for /boot.
Anyways, the real problem is, that convert_raid1 gives the wrong results
because the output format of mdadm has changed. Do you know if the
output format of /proc/mdstat is stable? If so, we could use that
instead of "mdadm -D -b".
