In some cases the third location has a single IP and it makes sense to use it as QDevice. If it has multiple network connections to that location - use a full blown node .

No. > does it only use the one specified under the quorum directive for QDevice? Yes. Remote device is unrelated to corosync rings. Qdevice receives information of current cluster membership from all nodes (point of view), computes partitions and selects partition that will remain quorate. _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
