Right. Dan's comment gave me pause: it does not seem to be
a good idea to assume a RBD image of an infinite size. A friend who read this
thread suggested a sensible approach (which also is in line with the
Haystack paper): instead of making a single gigantic image, make
multiple 1TB images. The index is bigger
SHA256 sum of the artifact => name/uuid of the 1TB image,offset,size
instead of
SHA256 sum of the artifact => offset,size
Just my 2 cents:
You could use the first byte of the SHA sum to identify the image, e.g.
using a fixed number of 256 images. Or some flexible approach similar to
the way filestore used to store rados objects.

Burkhard
