nova.conf

I'm attaching nova.conf from an environment which shows the same issue. Note: I wasn't able to complete the Nova upgrade because it's still WIP - https://review.openstack.org/#/c/405241/ . Maybe we need to change these config options to the new required values during the upgrade steps?

Comment 4 Diana Clarke 2017-01-20 15:34:26 UTC

Reassigning to Steven Hardy, as I suspect this will be addressed by the following WIP (see review comments where this bug is mentioned):

 - Add nova service support for composable upgrades
 - https://review.openstack.org/#/c/405241/

Related nova conf change:

 - Backwards incompatible change introduced here:
 - https://review.openstack.org/#/c/332861/13/nova/conf/service.py

Related tripleo bugs:

 - Can't deploy overcloud with ocata/trunk on rhel
 - https://bugs.launchpad.net/tripleo/+bug/1633735

 - nova's osapi_compute_workers is not valid (must be greater than 1)
 - https://bugs.launchpad.net/tripleo/+bug/1631133

Thanks Steven! Do let me know if want/need any help on this front.

Have a great weekend!

Comment 6 Sofer Athlan-Guyot 2017-03-21 18:40:05 UTC

Hi several patch landed for nova and have landed downstream so I think this bug can be closed, Yurii can you confirm ?

Comment 7 Sofer Athlan-Guyot 2017-03-21 18:42:49 UTC

Sorry, please change "several patch(es) landed for nova" to "the patch landed upstream"

Comment 8 Marius Cornea 2017-03-22 11:29:59 UTC

I think we can consider this as solved as currently the correct configuration gets applied by puppet during the upgrade workflow.
