Description of problem: Very bad things happen (indefinite hang / silent failure) when SSH host keys are not accepted for both Gluster and ovirtmgmt interfaces. Specifically, we need cleanup Chapter 5. One very long sentence that specifically mentions the "management" interface followed by a large "Important" block that contradicts the previous sentence is not good. Version-Release number of selected component (if applicable): RHHI 1.5 / RHV 4.2.7 Additional info: https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.5/html-single/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/#task-configure-key-based-ssh-auth I suggest simplifying the chapter by just saying this: " !!!Important!!! RHHI for Virtualization requires key-based SSH authentication without a password. Ensure that the first node has already logged into each of the machines, including itself. Do this for ***all storage and management network interfaces.*** Check the contents of /root/.ssh/known_hosts to validate. For example [root@host1 ~]# cat /root/.ssh/known_hosts ### Management FQDNs ### host1.example.com,192.168.0.101 ecdsa-sha2-nistp256 AAAA... host2.example.com,192.168.0.102 ecdsa-sha2-nistp256 AAAA... host3.example.com,192.168.0.103 ecdsa-sha2-nistp256 AAAA... ### Storage IPs ### 192.168.255.201 ecdsa-sha2-nistp256 AAAA... 192.168.255.202 ecdsa-sha2-nistp256 AAAA... 192.168.255.203 ecdsa-sha2-nistp256 AAAA...

The changes are made as per requirement and are clear in RHHI4V documentation. Hence moving the bug to verified state.
