BTW, is it now possible to alter nodelist at runtime (remove some nodes from there)?

Do I need to do it on every node or just on one? And, it should not be allowed to set it lower than number of votes from currently active nodes. Probably even not lower than number of votes from nodes which are now either active or inactive but joined at least once (I suppose that nodelist is fully editable at runtime, so admin may some-how reset join count of node and only than reduce expected_votes). > > I think this should fulfill your requirements. Great, that is what I need. Thanks, Vladislav _______________________________________________ discuss mailing list discuss@xxxxxxxxxxxx http://lists.corosync.org/mailman/listinfo/discuss
