Hi Abhishek Yes, before trying the: glance location-add --url rbd://8162f291-00b6-4b40-a8b4-1981a8c09b64/images-prod/6bcc4eab-ed35-42dc-88bd-1d45de73b628/snap 6bcc4eab-ed35-42dc-88bd-1d45de73b628 command, I uploaded the image to ceph. And indeed I can see it: [root@ceph-mon-01 ~]# rbd info images-prod/6bcc4eab-ed35-42dc-88bd-1d45de73b628 rbd image '6bcc4eab-ed35-42dc-88bd-1d45de73b628': size 10GiB in 1280 objects order 23 (8MiB objects) block_name_prefix: rbd_data.b7b56aa1e4f0bc format: 2 features: layering flags: create_timestamp: Tue Aug 27 11:42:32 2019 [root@ceph-mon-01 ~]# rbd snap ls images-prod/6bcc4eab-ed35-42dc-88bd-1d45de73b628 SNAPID NAME SIZE TIMESTAMP 455500 snap 10GiB Tue Aug 27 11:46:37 2019 [root@ceph-mon-01 ~]# Cheers, Massimo On Tue, Aug 27, 2019 at 2:41 PM Abhishek Kekane <akekane@redhat.com> wrote:
Hi Massimo,
I need to reproduce this first, but pretty much sure this issue is not because you configured multiple backends. What you are doing is downloading existing image to your local storage and then uploading it to glance using add-location operation.
So before adding this using add-location operation have you manually uploaded this image to ceph/rbd? if not then how you are building your location url which you are mentioning in the add-location command? If this location is not existing then it might be a problem.
Thank you,
Abhishek

I have a Rocky installation where glance is configured with multiple backends. This [*] is the relevant part of the glance configuration.
I now need to dismiss the file backend and move the images-snapshots stored there to rbd.
I had in mind to follow this procedure (already successfully tested with an older version of OpenStack):
1) download the image from the file backend (glance image-download --file <file> <imageid> 2) upload the file <file> to rbd, relying on this function: https://github.com/openstack/glance_store/blob/stable/rocky/glance_store/_dr... 3) glance location-add --url rbd://xyz <imageid> 4) glance location-delete --url file://abc <imageid>
I have problems with 3:

As far as I can see with the "openstack" client there is not something to add/delete a location. So I guess it is necessary to change the 'direct_url' and 'locations' properties.
If I try to change the direct_url property:
# openstack image set --property direct_url='rbd://8162f291-00b6-4b40-a8b4-1981a8c09b64/images-prod/6bcc4eab-ed35-42dc-88bd-1d45de73b628/snap' 6bcc4eab-ed35-42dc-88bd-1d45de73b628 403 Forbidden: Attribute 'direct_url' is read-only. (HTTP 403)
Any hints ? Thanks, Massimo
