During boot up, I get the following messages:

mdadm: only specify super-minor once, super-minor=4 ignored.
mdadm: only specify super-minor once, super-minor=1 ignored.
mdadm: only specify super-minor once, super-minor=6 ignored.
mdadm: only specify super-minor once, super-minor=0 ignored.
mdadm: only specify super-minor once, super-minor=3 ignored.
mdadm: only specify super-minor once, super-minor=5 ignored.
mdadm: only specify super-minor once, super-minor=2 ignored.


I figured out that these messages are also generated by:

mdadm --examine --scan


This is what I have in mdadm.conf, which was created
during installation of fedora core 3:

# mdadm.conf written out by anaconda
DEVICE partitions
MAILADDR root
ARRAY /dev/md4 super-minor=4
ARRAY /dev/md1 super-minor=1
ARRAY /dev/md6 super-minor=6
ARRAY /dev/md0 super-minor=0
ARRAY /dev/md3 super-minor=3
ARRAY /dev/md5 super-minor=5
ARRAY /dev/md2 super-minor=2



Is it right that the warning messages above were a result
of specify the "super-minor" parameter in mdadm.conf file ...
given that the minor number could be determined from /dev/mdX,
where X is the minor number according to mdadm.conf:

super-minor=
The value is an integer which indicates the minor number
that was stored in the superblock when the array was cre-
ated. When an array is created as /dev/mdX, then the minor
number X is stored.


Also, can the output of 'mdmad --detail --scan' replace
the contents in mdadm.conf ? Here's what I get with 'mdadm --detail --scan':

I like the output better above, since it exactly says
which partitions are part of the raid 1 array.
