What does the message "waiting for quorum device Qdevice poll" mean?

Issue

• The fence device is not triggered after a node lost communication in the cluster and displays the message "waiting for quorum device Qdevice poll (but maximum for 30000 ms)".

• The corosync-qdevice is waiting 30 seconds to recalculate the votes when a node is lost in order to trigger fencing.
