Title: glance allows delete even if cannot be deleted from ceph backend store Status in OpenStack Glance backend store-drivers library (glance_store): In Progress Bug description: The following steps *should* reproduce the issue. Basically, if I have a copy-on-write cloned vol from image, glance allows me to delet the image from glance itself even if the image cannot be deleted from backend store thus requiring manual deletion from Ceph cluster. Upload an image to Glance. This will create a snapshot of the raw image. glance image-create --name="testimage" --is-public="true" --disk- format="raw" --container-format="ovf" < precise-server-cloudimg- amd64-disk1.img Create a cinder volume clone of the image nova volume-create --image-id <img-id> --display-name test-vol 4 When can then see that we have a snaphot image in the glance/images pool and a cloned image in the cinder/volumes pool rbd -p images ls| grep <img-id> # returns <img-id> rbd -p volumes ls| grep vol-<vol-id> # returns vol-<vol-id> Now if I delete the glance image... glance delete <img-id> I get a failure as expected since the snapshot is in use Request returned failure status.

(HTTP 500) But the image has been deleted from glance so there is no trace of it other than in Ceph itself glance index| grep <img-id> # returns nothing Now if I delete the cloned volume... nova volume-delete <vol> The rbd image is still around and I have no way of deleting it other than going into Ceph and manually deleting it. rbd -p images ls| grep <img-id> # returns <img-id> rbd -p volumes ls| vol-<vol-id> # returns nothing I suggest we disallow deleting the image from Glance if it is 'in-use'. Perhaps we could even give the user info on who/what is using the image so they can resolve dependencies.
