Thanks for putting this up in the ML. Replying inline:

I've looked at https://github.com/redhat-openstack/tripleo-quickstart-utils/blob/master/roles/validate-ha/tasks/main.yml
and I see it's basically a set of tasks that validates that HA is
working well on the overcloud.
Despite little things that might be adjusted (calling bash scripts
from Ansible), I think this role would be a good fit with
tripleo-validations projects, which is "a collection of Ansible
playbooks to detect and report potential issues during TripleO
deployments".

IMHO (and tell me if I'm wrong), this role is something you want to
apply at Day 1 during your deployment, right?
If that's the case, I think the playbooks could really live in THT
where we already have automation to deploy & configure Pacemaker with
Heat and Puppet.
Some tasks might be useful for the upgrade operations but we also have
upgrade_tasks that use Ansible, so possibly easily re-usable.

If it's more Day 2 operations, then we should investigate by creating
a new repository for tripleo with some playbooks useful for Day 2, but
AFIK we've managed to avoid that until now.

Same as stonith. It sounds like some tasks done during initial
deployment to enable instakce HA and then during upgrade to disable /
enable configurations. I think it could also be done by THT like
stonith configuration.

Great, it means we could easily re-use the bits, modulo some technical
adjustments.

I would suggest to move it to tripleo-docs, so we have a single place for doc.

versus
IIRC, everything in this repo could be moved to existing projects in
TripleO that are already productized, so little efforts would be done.
