1/ show us what the result of --examine was.
2/ add -vvv to the --assemble and report the result of that.

  3/ report the output of "mdadm -X /dev/list-of-devices"

Strangely this line is unique.  Every other device has:

           Name : 'RAID-Server':0

Where do those "'"s come from???

	I have no idea.

What exactly is listed in mdadm.conf for /dev/md0??

cat /etc/mdadm/mdadm.conf

I just spotted something not quite right.  Line 7 is missing a drive 
(/dev/sda).   That shouldn't prevent it from assembling, though.

Other than that everything looks OK.  The array hasn't been marked as
having a bitmap, but the bitmap seems to have been created correctly,
but not activated yet.

And you didn't provide the output of
   mdadm --assemble -vvv ....

	Oh, sorry!  I thought the fact I got it to assemble meant I didn't need to 
issue the command again...

	Indeed, it won't let me issue it again.  it says:

RAID-Server:/etc/cron.d# mdadm -A /dev/md0 /dev/sd[a-j] -vvv
mdadm: device /dev/md0 already active - cannot assemble it

	Should I stop the arraya nd re-assemble it with -vvv?

	Also, what about my question about the bitmap?  Should I delete it, despite 
the fact mdadm says there isn't one, or should I attempt to add it again, or 
should I wait until I do the checkarrray?
