Public bug reported: I hit an extra exception during a failed live migration rollback. This exception occurred on the destination node. This bug is not about the reason for the failed migration, but for the failure in the rollback.
The exception: Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/oslo_messaging/rpc/server.py", line 157, in _process_incoming res = self.dispatcher.dispatch(message) File "/usr/local/lib/python2.7/dist-packages/oslo_messaging/rpc/dispatcher.py", line 213, in dispatch return self._do_dispatch(endpoint, method, ctxt, args) File "/usr/local/lib/python2.7/dist-packages/oslo_messaging/rpc/dispatcher.py", line 183, in _do_dispatch result = func(ctxt, **new_args) File "/opt/stack/nova/nova/exception_wrapper.py", line 77, in wrapped function_name, call_dict, binary) File "/usr/local/lib/python2.7/dist-packages/oslo_utils/excutils.py", line 220, in __exit__ self.force_reraise() File "/usr/local/lib/python2.7/dist-packages/oslo_utils/excutils.py", line 196, in force_reraise six.reraise(self.type_, self.value, self.tb) File "/opt/stack/nova/nova/exception_wrapper.py", line 68, in wrapped return f(self, context, *args, **kw) File "/opt/stack/nova/nova/compute/manager.py", line 5090, in remove_volume_connection driver_bdm.driver_detach(context, instance, connector, TypeError: driver_detach() takes exactly 5 arguments (6 given) In compute manager.remove_volume_connection, this line calls driver_detach: driver_bdm.driver_detach(context, instance, connector, self.volume_api, self.driver) This is driver_detach in block_device.DriverVolumeBlockDevice: def driver_detach(self, context, instance, volume_api, virt_driver): The connector seems to be the culprit. ubuntu xenial/libvirt/pike... commit c2c6960e374351b3ce1b43a564b57e14b54c4877 Merge: 8d9eb67 95c190c Author: Jenkins <jenk...@review.openstack.org> Date: Mon May 15 17:45:36 2017 +0000 Merge "Make discover_hosts only query for unmapped ComputeNode records" ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
