Pacemaker will. But this is probably not gonna solve your problem as the fact who is primary and who secondary (master/slave role in pacemaker-terms) doesn't say anything about from which of the disks which part of the data is being taken. Primary just means that the drbd-device is being accessed from that side (btw. can be on both sides provided you are using a filesystem that can cope with that). Although it is not recommended drbd can be configured to automatically recover - by deletion of the changes on one side done during split-brain-phase. https://www.drbd.org/en/doc/users-guide-83/s-split-brain-notification-and-recovery > > > > _______________________________________________ > Users mailing list: Users@clusterlabs.org > http://clusterlabs.org/mailman/listinfo/users > > Project Home: http://www.clusterlabs.org > Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf > Bugs: http://bugs.clusterlabs.org
