You still want to configure fencing, but you can use the 'crm-fence-peer.sh' handler. Using this with 'resource-and-stonith' will tell DRBD to block I/O until the fence succeeds, preventing it from going dual-primary (even if just for the brief moment between fault and fence). -- Digimer E-Mail: digi...@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?" _______________________________________________ drbd-user mailing list drbd-user@lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
