Dear All, I has implemented the HA on dual stack servers, Firstly, I doesn't deploy IPv6 record on DNS yet. The CMAN and PACEMAKER can work as normal. But, after I create AAAA record on DNS server, i found the error that cann't start CMAN. Are CMAN and PACEMAKER support the IPv6? Regards, T. Kittiratanachai (Te)
