/etc/mdadm.conf is there, I have even tried to copy it 
to /etc/mdadm/mdadm.conf and the error is still there.
No initrd/iniramfs on this system.

Any ideas why mdadm (mdadm -As) can not find my arrays at boot time.

Is /etc/mdadm.conf the correct location?  Debian uses 
/etc/mdadm/mdadm.conf.  Are you using a special initrd/initramfs boot 
method?

[gentoo-user] Errormessage from mdadm at boot

[Dan Johansson]

As dmraid is hard masked and it's future doesn't look to bright I have decided 
to give software raid a try 
(http://www.gentoo.org/doc/en/gentoo-x86-tipsntricks.xml). Everything works 
fine with one exception, when I boot the system I'm getting the following 
error:
Starting up RAID devices (mdadm)
mdadm: No arrays found in config file

But the system comes up correctly. My /etc/mdadm.conf file contains the 
following:
ARRAY /dev/md4 level=raid1 num-devices=2 
UUID=f03ab886:29539a16:60351ac2:644491c6
ARRAY /dev/md3 level=raid1 num-devices=2 
UUID=b4721e3b:7eab0b51:231a400e:3e228ff3
ARRAY /dev/md2 level=raid1 num-devices=2 
UUID=b660191e:81583b46:491c57c8:2ebb62b2
ARRAY /dev/md1 level=raid1 num-devices=2 
UUID=f3134895:0a4f292b:8b078635:1f67f091

and cat /proc/mdstat gives:
Personalities : [raid1]
md1 : active raid1 hdc1[1] hda1[0]
  32000 blocks [2/2] [UU]
md2 : active raid1 hdc2[1] hda2[0]

  497920 blocks [2/2] [UU]
md4 : active raid1 hdc4[1] hda4[0]
  79377088 blocks [2/2] [UU]
unused devices: 

Any ideas why mdadm (mdadm -As) can not find my arrays at boot time.
