Create a new failover domain, attempt to add nodes on the failover domain screen. The nodes will not actually be added to the failover domain.
This seems to happend when no checkboxes are checked in the failover domain screen.
I confirm that this happens in all conditions. Either if you have all checkboxes off, on or some on and some off, the generated failover domain is empty.
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
