Doc Text:
During an upgrade from Red Hat OpenStack Platform (RHOSP) version 9 to version 10, credentials from RHOSP 9 are carried over until convergence, when the full upgrade is completed. This causes alarm evaluation to fail. Manually update options in '[service_credentials]' section: 1. Set auth_type to password: auth_type=password 2. os_* options are no longer valid. Remove os_* prefix from the following options: os_username - replace with username os_tenant_name - replace with project_name os_password - replace with password os_auth_url - replace with auth_url os_region_name - replace with region_name 3. Remove 'v2.0' version from auth_url auth_url=http://[fd00:fd00:fd00:2000::10]:5000/ 4. Restart the service: systemctl restart openstack-aodh-evaluator.service Aodh alarms will now be evaluated correctly.

Description of problem:
-----------------------

Credentials from osp9 are carried over until converge, causing alarm evaluation to fail with next traceback in aodh/evaluator.log:

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
puppet-aodh-9.4.1-1.el7ost.noarch
openstack-aodh-evaluator-3.0.1-4.el7ost.noarch
python-aodh-3.0.1-4.el7ost.noarch
openstack-aodh-common-3.0.1-4.el7ost.noarch
openstack-aodh-api-3.0.1-4.el7ost.noarch

python-aodhclient-0.7.0-1.el7ost.noarch
openstack-aodh-notifier-3.0.1-4.el7ost.noarch


Steps to Reproduce:
-------------------
1. Upgrade from RHOS-9 to RHOS-10
2. After 'Controller And Block Storage Upgrade' step check aodh/evaluator.log


Actual results:
---------------
Traceback in log. Alarms ain't evaluated.


Expected results:
-----------------
Aodh is working through the upgrade

Additional info:
----------------
Workaround is to manually update options in '[service_credentials]' section:
1. Set auth_type to password:
   auth_type=password

2. os_* options ain't valid anymore, remove os_* prefix

os_username    -> username
os_tenant_name -> project_name
os_password    -> password
os_auth_url    -> auth_url
os_region_name -> region_name
 
3. Remove 'v2.0' version from auth_url
   auth_url=http://[fd00:fd00:fd00:2000::10]:5000/
Comment 1 Yurii Prokulevych 2016-12-14 09:40:57 EST 
And after aforementioned changes restart openstack-aodh-evaluator.service
Comment 2 Sofer Athlan-Guyot 2016-12-14 10:06:15 EST 
Oki, so this is in-transition error.

In the end, after the aodh migration we have this in the configuration:

    auth_type = password

    auth_url=http://192.0.2.6:35357

    [service_credentials]
    region_name = regionOne
    auth_type = password
    auth_url = http://172.16.2.4:5000
    project_name = service
    project_domain_id = default
    username = aodh
    user_domain_id = default
    password = zr8MzHpjWZH9A6sQhVUdtkZPC

(note that the os_* entries are still there, but it doesn't affect
operation)

So this is as expected and the aodh service is working.

The issue here is that after controller upgrade and after convergence
or aodh migration the service will be non-working.

Maybe could be solved by a doc warning ?
Comment 3 Yurii Prokulevych 2016-12-14 10:12:33 EST 
Hi Sofer,

Totally agree this is transitory issue and it's 'fixed' after the whole upgrade process is finished.
But since it might take quite a long we need to document this limitation and a workaround to bypass it.
