If you can figure out which block prefix the images used, you can
reconstruct the header enough to make the image accessible again.
Check out this thread:
http://comments.gmane.org/gmane.comp.file-systems.ceph.devel/7775
Do you know how the header object became missing? Did you have any
issues with your cluster, or scrub errors? If you're mysteriously
missing these header objects, other objects storing the data for the
image might be missing as well, which could cause strange errors
later.
