Can you explain what you did?

The best way to fix this is to initialize the corrupt id file and
activate the domain.

You can easily copy the images to another file based storage (nfs,
gluster) like this:

1. activate other storage domain using engine
2. mount gluster domain manually
3. copy the image from gluster domain to the other domain:

cp -r gluster-domain-mountpoint/images/image-uuid
/rhev/data-center/mnt/server:_path/other-domain-uuid/images/

But the images will not be available since engine does know them.
Maybe this can be
fixed by modifying engine database.

Another solution (if you are using ovirt 4.0), is to upload the images
to a new disk,
and attach the disk to the vm instead of the missing disk.
