Description Cédric Jeanneret 2019-12-11 14:38:02 UTC

Description of problem:
The /var/lib/mistral/<overcloud stack name> directory is dropped when a scaledown is over. This prevent any debugging.

It might be within tripleo-common or tripleoclient - not really sure about the component.

Version-Release number of selected component (if applicable):
openstack-tripleo-common-containers-11.3.2-0.20191127200418.5c82293.el8ost.noarch
python3-tripleo-common-11.3.2-0.20191127200418.5c82293.el8ost.noarch
openstack-tripleo-common-11.3.2-0.20191127200418.5c82293.el8ost.noarch
python3-tripleoclient-12.3.1-0.20191202211445.46c5fb4.el8ost.noarch

How reproducible:
Always

Steps to Reproduce:
1. Deploy Director + Overcloud
2. Remove an overcloud node (Compute for instance)
3. Check the existence of /var/lib/mistral/<overcloud stack name>

Actual results:
The directory is removed at some point

Expected results:
The directory should be there

Removed a compute-1 from an overcloud with two computes:

Before test:

+--------------------------------------+--------------+--------+------------------------+----------------+------------+

After compute-1 removed:

+--------------------------------------+--------------+--------+------------------------+----------------+------------+

/var/lib/mistral/overcloud is still present after compute-1 removed:
