There was RAID-1 device created of two partitions of the similar size on two disks. Disks are not of the same size and there are other (non-RAID) partitions.
During clean install of 13.04, I haven't touched those two partition (left them unformatted and assigned to anything) and now have newly installed system with old (non-RAID) partition regularly accessible. And I have those two partition which were part of RAID-1 device and they are unreadable.
I would like to create RAID-1 using those two partitions. Is it possible to do it, get functional RAID-1 and gain back access to data stored there?
