Since that one\u0027s been approved, Cinder is on track to take advantage of Glance multiple stores via the volume-type.  What you need to say here is that volume-type store specification is nice, but it doesn\u0027t allow for co-location (unless the image was already in the glance store defined by that volume-type).  Also, it depends on the operator configuring the volume-type extra-specs to define a preferred Glance store; if the operator doesn\u0027t take this step, all uploads go to the default Glance store.\n\nAlso mention somewhere that the way Cinder gets the store_id from the volume-type extra-specs to Glance is via the \u0027x-image-meta-store\u0027 header.","commit_id":"4aa49dbe53b3e653260d5985a9cd17168695ed8d"},{"author":{"_account_id":9303,"name":"Abhishek Kekane","email":"akekane@redhat.com","username":"abhishekkekane"},"change_message_id":"0784d68b55e152435e8f5106734cc8e18d6fca0d","unresolved":false,"context_lines":[{"line_number":22,"context_line":"is not specified at the time of uploading an image then the image"},{"line_number":23,"context_line":"will be stored in default store."},{"line_number":24,"context_line":""},{"line_number":25,"context_line":"In case of cinder copying volume to image, if no changes are made to"},{"line_number":26,"context_line":"cinder, even if multiple stores are configured then the image will be"},{"line_number":27,"context_line":"uploaded to default store.
