Here you go. I warn you it is a bit long!

Thanks.  Length is no problem.

Only it doesn't make sense at all.  I cannot see how mdadm would possibly be
generating just those messages.
It appear to be rejecting each device for some reason, but it not reporting
why it is rejecting the device...

What version of mdadm is this?
    mdadm --version

I should have asked that before.

I think John said 2.6.9 on the CentOS 5.5 rescue media. I think it's 
time to try something more recent: John, could you try SystemRescueCD 
from http://www.sysresccd.org/ and run
   mdadm -Evvs
and if that shows your RAID5 members again,
   mdadm -Afvv /dev/md1

Cheers,

John.
