An example of these entries is given below.

Clean Trilio Keystone resources

Trilio registers services and users in Keystone. Those need to be unregistered and deleted.

openstack service delete dmapi
openstack user delete dmapi
openstack service delete TrilioVaultWLM
openstack user delete triliovault

Clean Trilio database resources

Trilio creates databases for dmapi and workloadmgr services. These databases need to be cleaned.

Login into the database cluster

podman exec -it galera-bundle-podman-0 mysql -u root

Run the following SQL statements to clean the database.

## Clean database
DROP DATABASE dmapi;

## Clean dmapi user
=> List 'dmapi' user accounts
MariaDB [mysql]> select user, host from mysql.user where user='dmapi';

Revert overcloud deploy command

Remove the following entries from roles_data.yaml used in the overcloud deploy command.

• OS::TripleO::Services::TrilioDatamoverApi

• OS::TripleO::Services::TrilioWlmApi

• OS::TripleO::Services::TrilioWlmWorkloads

• OS::TripleO::Services::TrilioWlmScheduler

• OS::TripleO::Services::TrilioWlmCron

• OS::TripleO::Services::TrilioDatamover

In the case that the overcloud deploy command used prior to the deployment of Trilio is still available, it can directly be used.

Follow these steps to clean the overcloud deploy command from all Trilio entries.

1. Remove trilio_env.yaml entry

2. Remove trilio endpoint map file Replace with original map file if existing

Revert back to the original RHOSP Horizon container

Run the cleaned overcloud deploy command.
