Looks a valid bug for Cinder (or at least some kind of Glance<->Cinder interlaced issue). Either way, moving it to the cinder team.
** Project changed: nova => cinder -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1871861 Title: Share the snapshot of volume-backed instance to other tenant, but can not build instance with this image. Status in Cinder: New Bug description: Create a snapshot(image) of a volume-backed instance, this will generate a image in glance. At first, this image is private, I can update this image's visibility to shared, and execuate glance member- create and glance member-update on this image to share image to another tenant. Then another tenant use this image to create a new instance, it will failed of this message "HTTP exception thrown: Block Device Mapping is Invalid: failed to get snapshot xxx" From the analysis of logs and nova code, it is because nova-api will call _validate_bdm function to get snapshot from cinder, but in cinder, the added tenant can not see the volume snapshot, the snapshot is not belong to the tenant, so cinder-api will return 404 when nova- api call get_snapshot. How can I make this process to succeed? ====steps======== 1. show the snapshot of volume-backed instance # glance image-show a13fe7a1-e001-41c8-8119-70d5090cb7b0 +----------------------+----------------------------------------------------------------------------------+ | Property | Value | +----------------------+----------------------------------------------------------------------------------+ | base_image_ref | | | bdm_v2 | True | | block_device_mapping | [{"guest_format": null, "boot_index": 0, "delete_on_termination": false, | | | "no_device": null, "snapshot_id": "7a1b5060-e58c-4244-bb61-4ccef0295a1f", | | | "volume_type": null, "device_name": "/dev/sda", "disk_bus": "scsi", "image_id": | | | null, "source_type": "snapshot", "tag": null, "device_type": "disk", | | | "volume_id": null, "destination_type": "volume", "volume_size": 50}] | | boot_roles | heat_stack_owner,myrole,swiftuser | | checksum | d41d8cd98f00b204e9800998ecf8427e | | container_format | bare | | created_at | 2019-12-02T06:31:36Z | | disk_format | qcow2 | | hw_disk_bus | scsi | | hw_qemu_guest_agent | yes | | hw_scsi_model | virtio-scsi | | hw_video_model | qxl | | id | a13fe7a1-e001-41c8-8119-70d5090cb7b0 | | locations | [{"url": "rbd://4ffaf12a-099d-4297-a22e- | | | f8c16c17d6e3/images/a13fe7a1-e001-41c8-8119-70d5090cb7b0/snap", "metadata": {}}] | | min_disk | 50 | | min_ram | 0 | | name | fhl-volume | | os_distro | centos | | os_hash_algo | sha512 | | os_hash_value | cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0 | | | ff8318d2877eec2f63b931bd47417a81a538327af927da3e | | os_hidden | False | | os_type | linux | | owner | 17bf57ec04994db2b591fda36c368e99 | | owner_project_name | myproject | | owner_user_name | myuser | | protected | False | | root_device_name | /dev/sda | | size | 0 | | status | active | | tags | [] | | updated_at | 2020-04-09T09:40:57Z | | virtual_size | Not available | | visibility | private | | vm_mode | hvm | +----------------------+----------------------------------------------------------------------------------+ 2.
