So don't yet remove the supperblock. You could try to fix the array by
re-adding the failed drive with the --re-add command. To try that you
should boot your system from cd or usb-stick with the drives
connected. You can then check the status of the array with cat
/proc/mdstat. It then probably will be marked read-only. Stop the
array with mdadm --stop /dev/md127 (or whatever number it has then)
You then can try to reassemble the array with:
mdadm --assemble /dev/md* followed by the physical devices. It might
refuse te add the failed device. You can then try to readd it with:
mdadm --re-add /dev/md* /dev/<your device>
If it works you can create a new mdadm.conf file with:
mdadm --detail --scan --verbose > /etc/mdadm.conf
