Hi there

What RAID level of the set where the image is from?

AFAIK mdadm writes some "magic" to the device that is used as part of a
raid set. I would suggest that, if possible you dd out that data to
another disk and then use that. Otherwise you wousl have to abstract that
disk image as a device (FUSE could help) for mdadm to use, so that mdadm
can read/write into it, as it re-establishes the raidset, even if you
later mount it read only...
