OK, I upgraded my kernel and mdadm:

"uname -a":
Linux ned 2.6.13-grml #1 Tue Oct 4 18:24:46 CEST 2005 i686 GNU/Linux

"dpkg --list mdadm" --> "2.4.1-6"

Now I get slightly different messages. The problem seems to be
the superblocks. Can I repair them?

root@ned ~ # date;cat /proc/mdstat
Mon Jul 10 10:41:45 CEST 2006
Personalities : [linear] [raid0] [raid1] [raid5] [multipath]\
 [raid6] [raid10]
unused devices: <none>
root@ned ~ # mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1\
 /dev/sdc1 /dev/sdd1
mdadm: cannot open device /dev/sda1: Device or resource busy
mdadm: /dev/sda1 has no superblock - assembly aborted
root@ned ~ # mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1\
 /dev/sdc1 /dev/sdd1 --force
mdadm: cannot open device /dev/sda1: Device or resource busy
mdadm: /dev/sda1 has no superblock - assembly aborted
root@ned ~ #

If I omit the sda1, the message is repeated but with the missing
superblock of sdb1.
