It does not work for two node cluster (I do not mean necessary two_node=1). Only one of two nodes may be quorate in this case, which returns us to possible race condition in case of (unattended) shutdown. It is the same as with qdevice - everything works as long as we can ensure qdevice server remains up and reachable until all cluster nodes are stopped. _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
