Super something on external devices which are inactive?
They are all internal drives. That is the normal good state
for the arrays. After a reboot md124 would show auto-read-only
instead of active. When in that state I cannot mount the filesystem.

I think I would try to make it so that the mdtools figure out what the
arrays consist of automatically.  IIRC it is not necessary, maybe not
even advisable, to specify explicitly in mdadm.conf what the arrays are
made of because there is information stored on the disks that allow to
build them automatically.
The mdadm.conf was built when F18 was installed.
Running mdadm --detail --scan returns the same info as what is in the
conf file. I checked that already to make sure there was not any differences.

Is md124 a RAID-1 on top of a RAID-0?
Two separate arrays.

Thanks
Alan
