Title:
RBD backend errors are not raised correctly
Status in Glance:
New
Bug description:
glance_store 2014.2
When operation on RBD backend fail, e.g. by trying to open missing image in
RBD pool, glance_store tries to raise exception NotFound with incorrect
argument list, so glance API returns Internal Server Error 500.
Older version (2014.1) returns 404.
Steps to reproduce:
$ glance image-create --name test --disk-format qcow2 --container-format bare
--copy-from http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-i386-disk.img
# rbd -p images snap unprotect dbedacd2-a140-4816-a96d-b98ef610ddc3@snap
# rbd -p images snap rm dbedacd2-a140-4816-a96d-b98ef610ddc3@snap
# rbd -p images rm dbedacd2-a140-4816-a96d-b98ef610ddc3
# glance-cache-manage -f delete-all-cached-images # only if cache used
$ glance image-download --file img dbedacd2-a140-4816-a96d-b98ef610ddc3
