Hello. Thanks for the answer.Maybe I was not clear: I do not want the authomatic poweroff of the server.My problem is that if I manually poweroff the primary node (i.e. the server with DRBD primary mounted on), the secondary does not become primary (promote) anymore!It seems that the primary, just before powering off, fences the other node and precludes it to become primary. This not the expected logic in a two nodes cluster...Is there a way?
