The Overcloud deployment used a default port quota of 50 for Neutron networking, which caused failures in larger deployments. This fix disables the port quota. Larger Overcloud deployments no longer fail from lack of Neutron ports.

Description Ben Nemec 2015-07-14 20:08:51 UTC

Version-Release number of selected component (if applicable):

How reproducible: Always

Steps to Reproduce:
1. Deploy an overcloud with 3 controllers and 10 computes

Actual results: Deployment fails due to over quota errors on Neutron ports

Expected results: Successful deployment

Ben, any clarification to the workaround we want to put in the release doc?

Comment 5 Emilien Macchi 2015-07-14 20:59:27 UTC
This is the default in puppet-neutron: https://github.com/openstack/puppet-neutron/blob/master/manifests/quota.pp#L93
Because this is the default in Neutron:

If we need such a change, I would suggest to patch tripleo-heat-template to use the puppet class and change the parameter. Can be done quickly, please let me know.

Comment 8 Ben Nemec 2015-08-14 19:11:38 UTC
The workaround is to run "neutron quota-update --port -1" on the undercloud.

Chris, can you please set the severity field to "urgent" for this bug. We are using severity field to track the blocker issues.

Comment 12 chris alfonso 2015-09-17 15:21:08 UTC
Setting the severity to urgent won't change anything as far as when it's delivered. This bug is currently ON_QA, which means the bug is has been patched by a developer, and our quality engineering group is testing the fix. This bug also has a 'blocker' flag on it, which means it's critical and it must be part of the 7.1 release.
