Cause: The openstack UPI teardown scripts do not clear up Cinder volumes Consequence: Persistent volumes added to a UPI install are left untouched in the OpenStack cluster even after the teardown Ansible playbooks are successfully executed. Workaround (if any): Manually clear up any Cinder volume created in the cluster after teardown.

Description Pierre Prinetti 2020-03-31 08:46:42 UTC
+++ This bug was initially created as a clone of Bug #1814651 +++

Description of problem:

After creating a cluster using UPI scripts, we populate the internal registry and create cinder volumes from PVs

If destroy playbooks are executed, swift container is not deleted and also cinder volumes are still present on openstack


Version-Release number of the following components:
4.4.0-0.nightly-2020-03-18-092817

How reproducible:

Steps to Reproduce:
1.Install cluster using UPI on OSP
2.Populate internal registry and create PVs using the cinder storage class
3.Execute deletion playbooks

Actual results:
Following objects are still present in the cluster, after deletion is completed:
 - Cinder volumes from PVs
 - Swift container for image registry (bootstrap container is correctly deleted)

Expected results:
All cluster related objects are deleted

Additional info:
Please attach logs from ansible-playbook with the -vvv flag

--- Additional comment from Pierre Prinetti on 2020-03-23 11:12:09 UTC ---

In a UPI installation, the user should look after the resources they created.

A user will only use UPI if their architecture is fatally different from our Reference architecture; and those differences will likely render our teardown playbooks useless (and exponentially more so as we fine-tune them on a specific use-case).

It would indeed be handy if the playbooks did all the work the installer is doing. However for the very nature of UPI, those changes will overcomplicate the playbooks without relieving much of the user's work; they'll have to adapt the scripts anyway.

wdyt?

I think that UPI installer should remove all elements that the IPI installer does.

If not, we should include a disclaimer in the docs about which objects have to be manually removed when UPI uninstaller playbooks ends

Verified as change is only related to docs
