Cause:
Performing a 2nd deployment of OCP HA on existing bare metal machines may show the problem identified in BZ #1414414. We have not addressed 1414414 in QCI 1.1, ran out of time in cycle. Will address in 1.2, for 1.1 docs we want to call out that this potential problem exists for OCP HA deployments when performing a 2nd deployment of OCP HA on same hardware.
Consequence:
Deployment proceeds to 70% and errors out.
Workaround (if any):
Deleting Satellite and starting a QCI install from beginning is one workaround.
Result:
After reviewing this bug it seems that the actual problem occurs during the execution of the atomic-openshift installer. The error is shown below:
