Replied in doc.
Now the doc looks good to me.
There are few changes required: 1. Need for the fourth host was not explained well. The fourth host is to ensure that there is tolerance of failure of 1 host. If there are only 3 hosts in the cluster, failure of one host, will lead to situation, where heketi can't create any more replica 3 volume 2. Section - "Install the OpenShift Container Storage Host" This section looks as though some steps should be done on the fourth host. But this is not true. These are all the prerequisites for installing RHOCP on RHEL machines. I prefer to have this information under the subsequent section as pre-requisites reference. 3. Repositories should be enabled on all the hosts not only on master openshift-ansible is required only on master ( I suppose, need to confirm though.. ) 4. Configuring passthrough section should be made available ahead of the section to run the playbook. 5. Technically, the playbook should have the template host names as: master.example.com infra.example.com host1.example.com host2.example.com host3.example.com host4.example.com @Laura, I still have some small correction with the playbook, I will consult with dev and provide that information
Discussed offline with Laura, on the above points. The below article looks good. So closing the bug as verified https://access.redhat.com/articles/3895281 Also,canceling the needinfo on Laura.
