Dear All:
This is my first mail. I want to ask why the cinder driver instance id
changes in different request ? [ Openstack LIberty ]
I read from source code ,when service start ,VolumeManager init , the
volume driver init but I do not see the volume driver init or destroy any where
else;
but when I create two volumes ,I can see the id of volumedriver is
different from the log. I add the Log info as following:
#cinder.volume.manager.py
#def create_volume(self, context, volume_id, request_spec=None,
# filter_properties=None, allow_reschedule=True):
# """Creates the volume."""
# context_elevated = context.elevated()
# if filter_properties is None:
# filter_properties = {}
# if request_spec is None:
# request_spec = {}
# try:
# # NOTE(flaper87): Driver initialization is
# # verified by the task itself.
# LOG.info(_LI("="*40))
# LOG.info(_LI(str(self.driver)))
# LOG.info(_LI(id(self.driver)))
# LOG.info(_LI("="*40))
# flow_engine = create_volume.get_flow(
# context_elevated,
# self,
# self.db,
# self.driver,
# self.scheduler_rpcapi,
# self.host,
# volume_id,
# allow_reschedule,
# context,
# request_spec,
# filter_properties,
# image_volume_cache=self.image_volume_cache,
# )
the output line I have marked yellow and green,the part of the log as following:
