You can stop grub doing the root=uuid= thing by changing /etc/default/grub
If you can get someone to the keyboard, then you can probably get them
to edit what grub is using as a one-off - i.e. change the root=uuid=xxx
entry to root=/dev/md0 (or even just one half of the mirror if you need
to get it working, then you can fix it later)...
It's also worth checking the contents of /etc/mdadm/mdadm.conf is
sensible - maybe if you duplicated the partition (with dd maybe, if you
said you duplicated the UUID), then it contains an incorrect uuid= line?
If it's incorrect, you may need to regenerate the initramfs having
corrected it (a copy is placed in the initramfs files) with
"update-initramfs -k all -u"
In a similar situations, where I have no remote console (IPMI SoL, Intel
AMT etc.), I like to use "qemu -snapshot ..." to verify that a system
will boot up correctly by pointing it at the real hard disks (see recent
post to this list).
