Could not find declared class ::remote::db

[Hanxi Liu]

Hi folks,

I used rdo and packstack to deploy three controller nodes.
At the step of first node deployment, I set:
     CONFIG_MARIADB_INSTALL=n

When I ran
    packstack --answer-file=ocata-answer-file

the error occured:

ERROR : Error appeared during Puppet run: 192.168.2.171_controller.pp
Error: Evaluation Error: Error while evaluating a Resource Statement, Could not find declared class ::remote::db at /var/tmp/packstack/b560f3696df94015aeb04b3cb2e36ec5/modules/packstack/manifests/mariadb.pp:66:5 on node vm001

environment:
CentOS-7.3-1611-x86_64
OpenStack：Ocata
Ceph：Jewel

Thanks for the report. It looks like we need a couple fixes in the puppet-remote module.

I have proposed https://github.com/paramite/puppet-remote/pull/5 with the required changes, could you try them in your environment? The files to change should be located at /usr/share/openstack-puppet/modules/remote in your setup.

It's weird that the file under /usr/share/openstack-puppet/modules/remote/manifests is mysql.pp. I tried to rename mysql.pp to db.pp and use (versioncmp($::operatingsystemmajrelease, '7') <= 0) for comparison. Unfortunately, this
occurred: http://paste.openstack.org/show/609186/. So I check the database in mysql. There are databases such as nova, keystone but no tables. I wonder if there are some configurations i should pay more attention.

this is my ocata-answer-file: http://paste.openstack.org/show/609193/

I have proposed https://github.com/paramite/puppet-remote/pull/6 to fix incorrect file.

That new error seems to be related to the Nova Cells v2 additions in Ocata. I'll have a look.

I have had a successful installation combining both https://review.openstack.org/463599 and https://github.com/paramite/puppet-remote/pull/5

    Fix database configuration for remote MariaDB setups

    This seems to have been broken for a long time, when
    CONFIG_MARIADB_INSTALL is set to 'n' we where not setting the
    CONFIG_MARIADB_HOST_URL correctly.
