And it is also still "electable", that is it likely will become DC. So this is not an answer to the OP's question, or I misunderstood "electable" in that question. "in theory" you should be able to add a node on the membership layer only (corosync), but not start pacemaker. That "should" give you an additional quorum vote, but obviously won't be able to become DC. You could also say "pretty please" to beekhof, not taking part in the DC election should be a very simple if () statement in the code and one additional node setting in the cib, something like standby, only "stronger". Use case would be to add a weak, small, cheap, maybe even virtual, node to an otherwise two-node cluster to serve as a quorum tiebreaker. It may have not enough power to run resources, and possibly not even enough to run as DC. Or it may not be reliable enough all by itself to act as DC, rebooting it should not affect an otherwise healthy cluster at all etc. -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
