At the moment we're actually trying to remove the disk on failure.
However the disk_service.remove() API does nothing (doesn't even
fail). Perhaps because the transfer isn't finalized on the error
path?
That's weird, it should fail to acquire the disk's lock.
In any case, I think that removing the disk this way would be wrong as we
also store an entity in the image_transfer table that should be removed
(otherwise, another attempt to upload the same disk would probably fail).
Daniel/Nir, I can't find a way to cancel an ongoing upload-image operation
through the API (as we have in the webadmin), am I missing it or is it
missing?
Anyway the code - which needs review - is:
