Hi Lon Sorry Lon, but it is not completely clear again for me ... : when you write that default cman timeout on RHEL5 is 5 seconds, you mean that the heart-beat timeout is 5s ? whereas each hello message is sent every 5s too ? And the totem in cluster.conf to modify it was in my understanding the "deadnode_timer" in the cman record ... what is the "token" you mention ? And finally, my would be to set deadnode_timer="21s" for cman and to keep interval="1" and tko="10" for quorum disk. Just a precision, it on a only two nodes cluster with quorum disk. Thanks to confirm these points.
