Public bug reported: When the attached instance is lost, the related cinder volume will be orphan and cannot be delete any more. This may happen when the instance is removed but this information hadn't been transferred to cinder, e.g. maybe network issue. User is not able to delete the orphan volume because there're still some attachment with it. So user need to remove the attachment for the volume first.
The issue is: when user try to remove the attachment by click the button "Manage Attachments" for the orphan volume, GUI just shows: "Error: Unable to retrieve volume information. ", and cannot open the "Manage Attachments" dialog. Some info may help for this bug: To list the attachment: python-cinderclient\cinderclient\v3\attachments.py:VolumeAttachmentManager:list() To delete an attachment: python-cinderclient\cinderclient\v3\attachments.py:VolumeAttachmentManager:delete() ** Affects: horizon Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
