You did make a new mdadm.conf

with the correct devices for each array

right? If not try running and seeing if your arrays

come up. If they do

then copy /tmp/mdadm.conf to /etc/mdadm/mdadm.conf

mdadm --examine --scan --config=partitions >

/tmp/mdadm.conf mdadm

--assemble --scan --config=/tmp/mdadm.conf

Hmmm.  I was hoping what I'd been doing had been
"wrong" somehow, but what
you've got is pretty much what I did.  And here's the
output (which
confuses the living Hell out of me):

ARRAY /dev/md0 level=raid1 num-devices=2
UUID=f2de81aa:ccd40fc9:01dc0b99:e8df86c1
ARRAY /dev/md1 level=raid1 num-devices=2
UUID=837925b3:f9f0e1b1:02f450c9:474613c9
ARRAY /dev/md1 level=raid1 num-devices=2
UUID=b6af942c:119cd1fc:02f450c9:474613c9

(Note how the second half of the last two UUIDs is the
same, and the last
two UUIDs are both for /dev/md1.)

Guess it's time to go to the tapes, huh?

Thanks,

So basically all you have done is remove the drives from 1 machine and insert in another? I would really hope that, that would not trash data... I have never tried it mind. i did recently change my drive order though just unplugged and re-plugged in a completely new order.
