It appears that the release of taskflow 0.10.0 exposed an issue in the NetApp NFS drivers. Something changed that caused the sqlalchemy Volume object to be garbage collected even though it is passed into create_volume() An example error can be found in the c-vol logs here: http://dcf901611175aa43f968-c54047c910227e27e1d6f03bb1796fd7.r95.cf5.rackcdn.com/57/181157/1/check/cinder-cDOT-NFS/0473c54/ One way to get around whatever the issue is would be to change the drivers to not update the object directly as it is not needed. But this should not fail. Perhaps a more proper fix is for the volume manager to not pass around sqlalchemy objects. Something changed in taskflow, however, and we should just understand if that has other impact. -Alex -------------- next part -------------- An HTML attachment was scrubbed...
