If you have a primary and secondary note that once one of them recognizes that there is no connection to the other it should force it self into a state of "not running". In the case you have a reliable WAN connection which never make any problems of connectivity then DRBD is good and I would say that you will want to change the status manually. If you have a direct connection between the machines so that they both can know always each other state in a "mesh" like connectivity(2 wans on separated carriers) then you probably are in a good state and the only time you would get a split-brain situation is when the network connectivity between the two is being "split" or "down". You can always force the primary to get into a "bad" connection situation which prevents an after "split-brain" issues. I am almost sure that DRBD is for you. (this is a DRBD list right? cannot talk about other things?) Eliezer
