When requesting cinderclient to create a new attachment, it requires server_id as a required parameter which is not available when we're creating attachment from glance cinder store.
*** Bug 2036950 has been marked as a duplicate of this bug. ***
Verified on: python3-cinderclient-5.0.2-2.20220107174846.7e9e31c.el8ost.noarch Verified on: openstack-cinder-15.6.1-2.20220112174913.c093eda.el8ost.noarch On a recent bz2049130, we proved image uploading to Glance over Cinder works. I'll re-paste a part of that same verification here as it proves this bug is verified too. Where this bug not fixed, Glance image upload over Cinder would have failed. On a deployment with Glance over Cinder, over netapp iSCSI with multipath enabled: We successfully uploaded a cirros qcow2 image: (overcloud) [stack@undercloud-0 ~]$ glance image-show e8cf1375-c6cc-4e59-bfea-a84b2a4bec55 +----------------------------------+----------------------------------------------------------------------------------+ | Property | Value | +----------------------------------+----------------------------------------------------------------------------------+ | checksum | 443b7623e27ecf03dc9e01ee93f67afe | | container_format | bare | | created_at | 2022-02-13T12:47:48Z | | direct_url | cinder://abcbdf43-73f3-42b5-8545-f32f90fdcddb | --> Cinder backed. | disk_format | qcow2 | | id | e8cf1375-c6cc-4e59-bfea-a84b2a4bec55 | | min_disk | 0 | | min_ram | 0 | | name | cirros | | os_hash_algo | sha512 | | os_hash_value | 6513f21e44aa3da349f248188a44bc304a3653a04122d8fb4535423c8e1d14cd6a153f735bb0982e | | | 2161b5b5186106570c17a9e58b64dd39390617cd5a350f78 | | os_hidden | False | | owner | 055c71e6d74b444a8a637a12826e4491 | | owner_specified.openstack.md5 | | | owner_specified.openstack.object | images/cirros | | owner_specified.openstack.sha256 | | | protected | False | | size | 12716032 | | status | active |---> Active | stores | default_backend | | tags | [] | | updated_at | 2022-02-13T12:48:06Z | | virtual_size | Not available | | visibility | public | +----------------------------------+----------------------------------------------------------------------------------+ (overcloud) [stack@undercloud-0 ~]$ cinder service-list +------------------+--------------------------+------+---------+-------+----------------------------+-----------------+ | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason | +------------------+--------------------------+------+---------+-------+----------------------------+-----------------+ | cinder-backup | controller-1 | nova | enabled | up | 2022-02-13T12:50:08.000000 | - | | cinder-scheduler | controller-0 | nova | enabled | up | 2022-02-13T12:50:04.000000 | - | | cinder-scheduler | controller-1 | nova | enabled | up | 2022-02-13T12:50:06.000000 | - | | cinder-scheduler | controller-2 | nova | enabled | up | 2022-02-13T12:50:06.000000 | - | | cinder-volume | hostgroup@tripleo_netapp | nova | enabled | up | 2022-02-13T12:50:00.000000 | - | --> The netapp iSCSI backend. +------------------+--------------------------+------+---------+-------+----------------------------+-----------------+ Now this time lets try with a raw image: (overcloud) [stack@undercloud-0 ~]$ glance image-create --name rhel7.9.raw --disk-format raw --container-format bare --file rhel-server-7.9-update-9-x86_64-kvm.raw +------------------+----------------------------------------------------------------------------------+ | Property | Value | +------------------+----------------------------------------------------------------------------------+ | checksum | 1e45e025443492de8d6e4b38ec265abe | | container_format | bare | | created_at | 2022-02-13T13:01:49Z | | direct_url | cinder://c8f12ad0-16b6-415c-a82b-f52628429946 | | disk_format | raw | | id | 2628daec-9274-42e3-8a87-1f0aed015948 | | min_disk | 0 | | min_ram | 0 | | name | rhel7.9.raw | | os_hash_algo | sha512 | | os_hash_value | 9266d25c2b74881526a5807fd594d4a145db99cde1e52fdbbefcade841daaefffa18cef0eb131760 | | | 06369a91e5c6e7d72f1df2ae68d24d889e057236b9d59e77 | | os_hidden | False | | owner | 055c71e6d74b444a8a637a12826e4491 | | protected | False | | size | 10737418240 | | status | active |--> Also active. | stores | default_backend | | tags | [] | | updated_at | 2022-02-13T13:04:45Z | | virtual_size | Not available | | visibility | shared | +------------------+----------------------------------------------------------------------------------+ Good to verify, having shown that we successfully managed to upload/create 2 images to Glance which is backed by Cinder. This also proves cinderclient needs server_id parameter to create an attachment is working as expected.
Just want to clarify Tzach's final sentence in comment #8. When he says "This also proves cinderclient needs server_id parameter to create an attachment is working as expected", what he means is "This also proves <name-of-this-BZ> is working as expected". The backported fix that's the subject of this BZ makes it the case that the server_id parameter is no longer required when using cinderclient to create an attachment. (Apologies for being pedantic, but I can imagine someone reading through this BZ in a year or so and being really confused.)
Thanks for the needed clarification Brain, spot on.
