[cinder] volume_attachement entries are not getting deleted from DB

Hello I am using wallaby release openstack and having issues with cinder volumes as once I try to delete, resize or unshelve the shelved vms the volume_attachement entries do not get deleted in cinder db and therefore the above mentioned operations fail every time. I have to delete these volume_attachement entries manually then it works. Is there any way to fix this issue ? nova-compute logs: cinderclient.exceptions.ClientException: Unable to update attachment.(Invalid volume: duplicate connectors detected on volume Help will be really appreciated Thanks ! -- Thanks and Regards, Hemant Sonawane
