Ah, then it is a fresh install, inheriting data disks.
Then you probably keep the old boot disk. Perhaps you could try it and
find out if it still can mount the raid filesystem. If that is so,
perhaps data can be rescued. If you don't have a spare disk for a
backup, you might remove one side of the mirror and create it there,
then create again the raid in TW.
If you don't have the old boot disk, you can create a boot media on an
USB stick. You can use the 12.3 XFCE rescue image:
http://download.opensuse.org/distribution/13.2/iso/openSUSE-13.2-Rescue-CD-x86_64.iso
just cp it to the raw usb device, and boot it.
But leave that procedure as a last resource; wait for more comments or
ideas ;-)

Yes, I read his post. My idea was wrong, then.
