Description of problem:

Creating a bug report on behalf of my customer:

------------------------------------------------------------------------------

What problem/issue/behavior are you having trouble with?  What do you expect to see?
Initially, the overcloud deployment failed due to incorrect parameters in rhsm.yaml file. Later I removed the existing stack, fixed the template and tried to redeploy. But then it failed during the deployment due to permission issue on "/var/lib/mistral/stack1/.git/index"[1]. I tried updating the owner:group to mistral. But, no luck. To workaround the issue, I used different overcloud stack name.
