Please give some hints, thanks :-) Make sure that heartbeat and drbd use the same link (if you have the resources use NIC-bonding!!!) further more you should be using a stonith device (*device* _not_ ssh) to be really sure only one node survives an error. Personally I'm running a OpenVZ setup [1], which uses a script called mbhave to setup the heartbeat/drbd ressources. You may want to have a look at it cheers flip [1] http://forum.openvz.org/index.php?t=msg&goto=32740&; _______________________________________________ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
