[gentoo-user] mdadm: No arrays found in config file

[gentoo-user] mdadm: No arrays found in config file

[Jarry]

Hi,

I have noticed following message in /var/log/boot
(but I see them too early during boot-up):
...
  * Remounting root filesystem read/write ...  [ ok ]
  * Setting hostname to obelix ...             [ ok ]
  * Starting up RAID devices (mdadm) ...
mdadm: No arrays found in config file         [ !! ]
...

But I do have correct entries in /etc/mdadm.conf,
I created it with "mdadm --detail --scan >> /etc/mdadm.conf:

ARRAY /dev/md0 level=raid1 num-devices=2 
UUID=003fda39:c9fd7a80:2590ab77:4f666e20
...
ARRAY /dev/md8 level=raid1 num-devices=2 
UUID=9500d085:ab7ec189:f308114e:c88b3121

But despite of that message, all raid-partitions are recognised
and mounted correctly. Even "/etc/init.d/mdadm restart" works
without any complaint. So where is the problem?

I have the same symptoms.

I have been getting this for some time but was hesitant to post a bug. 
Although I get this message, my raid starts fine, and when shutting
down, I get an "OK" message that it is shutdown properly.

I tried a lot of stuff to get rid of this message with no results.

I believe the reason for this is that your partitions are of type 'fd'
When they have that id they are automagically found and started by the
kernel, and therefor there are nothing for mdadm to do.
But this is just a guess.

That would be my guess.  Similarly, if the root filesystem is on a
raid volume, the initramfs environment may start all raid volumes, and
there will be nothing for mdadm to do.

If either of these sounds right, you should be able to remove the
"raid" entry from RC_VOLUME_ORDER in /etc/conf.d/rc.

You are right on target.  This got rid of that message.

Thanks,
