Title:
Ironic driver requires extra_specs
Status in OpenStack Compute (Nova):
In Progress
Status in OpenStack Compute (nova) juno series:
In Progress
Bug description:
Comments on review https://review.openstack.org/#/c/111429/ suggested
that the Ironic driver should use
flavor = instance.get_flavor()
instead of
flavor = flavor_obj.Flavor.get_by_id(context,
instance['instance_type_id'])
During the crunch to land things before feature freeze, these were
integrated in the proposal to the Nova tree prior to being landed in
the Ironic tree (the only place where they would have been tested).
These changes actually broke the driver, since it requires access to
flavor['extra_specs'] -- which is not present in the instance's cached
copy of the flavor.
This problem was discovered when attempting to update the devstack
config and begin testing with the driver from the Nova tree (rather
than the copy of the driver in the Ironic tree). That patch is here:
https://review.openstack.org/#/c/119844/
The error being encountered can be seen both on the devstack patch
(eg, in the Nova code)
http://logs.openstack.org/44/119844/2/check/check-tempest-dsvm-
virtual-ironic-nv/ce443f8/logs/screen-n-cpu.txt.gz
and in the back-port of the same code to Ironic here:
http://logs.openstack.org/65/119165/3/check/check-tempest-dsvm-
virtual-
ironic/c161a89/logs/screen-n-cpu.txt.gz#_2014-09-08_08_41_06_821
==========
Proposed fix
==========
Fetch flavor['extra_specs'] on demand, when needed by the Ironic
driver.
