Description

Verified on:
python3-glance-store-1.0.2-1.20220110223456.el8ost.noarch
On a ceph backed deployment,
First I had to bump up the min client version
[root@controller-2 /]# ceph osd set-require-min-compat-client mimic
set require_min_compat_client to mimic
[root@controller-2 /]# ceph osd dump | grep client
require_min_compat_client mimic
min_compat_client jewel
FYI you must set this before you upload the image,
at first I had set it after the image was uploaded and verification failed.
First I uploaded a cirros image to glance:
(overcloud) [stack@undercloud-0 ~]$ glance image-list

+--------------------------------------+--------+
| 41427008-d91e-456f-89ef-5c435fc0d3ad | cirros |
+--------------------------------------+--------+
Now lets create a volume from this image:
(overcloud) [stack@undercloud-0 ~]$ cinder create 2 --image 41427008-d91e-456f-89ef-5c435fc0d3ad --name VOl1FromImage

+--------------------------------------+-----------+---------------+------+-------------+----------+-------------+
And now lets to delete the source image, which we should fail to do:
(overcloud) [stack@undercloud-0 ~]$ glance image-delete 41427008-d91e-456f-89ef-5c435fc0d3ad
Unable to delete image '41427008-d91e-456f-89ef-5c435fc0d3ad' because it is in use.
Image remains active:
(overcloud) [stack@undercloud-0 ~]$ glance image-show 41427008-d91e-456f-89ef-5c435fc0d3ad

And now lets create a new second volume from this image:
(overcloud) [stack@undercloud-0 ~]$ cinder create 2 --image 41427008-d91e-456f-89ef-5c435fc0d3ad --name VOl2After

And we successfully created a new volume from the image we attempted to delete:

Both volume from image are available, good to verify.
Before this fix the second volume would reach error state, as image would be broken.
