When upgrading for stable liberty to mitaka (current-passed-ci) after a yum update on the Undercloud, mariadb and keystone are down. Mariadb can't be restart, need to kill the mysql pid before, then the service is able to start. It looks like during the upgrade of the package mariadb can't stop the process and restart properly. Then keystone can't start because it trying to find the config_file: /usr/share/keystone/keystone-dist-paste.ini Which doesn't exist on the deployment. This issue is reproducible.
Ugh, stale bug, should probably be closed now.
