We do not have documentation about enabling nova quota if cluster deployed without it.

[Denis Klepikov]

We need a documentation that describe enabling nova quotas into cluster, deployed by fuel without selected check-box "Nova quotas" on settings tab into Fuel web UI.

We need to provide clear steps into our public documentation "How-To enable nova quotas on deployed cluster".

A good blog post on quotas - http://www.dorm.org/blog/nova-max_age-and-until_refresh-settings-for-easing-quotas-pain/

So this should look something like:

1) on controller nodes: set max_age=86400 and util_refresh=50 in nova.conf to make sure quota usage values are refreshed once a day or once per 50 VMs launched

2) on controller nodes: set quota_driver=nova.quota.DbQuotaDriver to enable quotas in Nova

3) on controller nodes: restarted nova services

   ubuntu: service nova-api restart; service nova-conductor restart
   centos: service openstack-nova-api restart; service openstack-nova-conductor restart

4) on controller nodes:

Add

 ENABLED_QUOTA_GROUPS = {
              'nova': True,
       }

to /usr/share/openstack-dashboard/settings.py

5) restart Horizon:

    ubuntu: service apache2 reload
    centos: service httpd reload
