Title:
swap volume is not available because the parameters are opposite
Status in OpenStack Compute (nova):
New
Bug description:
version: kilo
description:
in the fileļ¼/nova/compute/manager.py . the functions like this:
class _ComputeV4Proxy(object):
def swap_volume(self, ctxt, instance, old_volume_id, new_volume_id):
return self.manager.swap_volume(ctxt, instance, old_volume_id,
new_volume_id)
class ComputeManager(manager.Manager):
@wrap_exception()
@reverts_task_state
@wrap_instance_fault
def swap_volume(self, context, old_volume_id, new_volume_id, instance):
you see ,the parameters of instance should be in the right place .
product steps:
1 create a volume
2 create a vm
3 attach the volume to the vm
4 migrate the volume to another backend.
