On 2nd page of the wizard called "Select Hosts", try to configure Monitor only machine Actual results ============== One can't configure dedicated Monitor machine: 1. When one clicks on Monitor role icon to enable it for particular host, OSD is enabled automatically as well. 2. Then when one tries to deactivate this unwanted OSD, both OSD and Monitor roles are disabled. Expected results ================ One can configure dedicated Monitor machine. When Monitor role is enabled in "Select Hosts" page of the wizard, no other role is enabled with it. Additional info =============== Dedicated Monitor machine is completely valid Ceph configuration.
