The first fencing has finished with OK, as well as the other two fencing operations.

Aug 31 10:59:31 [30612] node1 stonith-ng:   notice: log_operation:     Operation 'reboot' [31075] (call 2 from crmd.30616) for host 'node2' with device 'st-fence_propio:0' returned: 0 (OK)

And the next log entries are:

After some other entries I see:

Aug 31 10:59:37 [30615] node1    pengine:  warning: pe_fence_node:     Node node2 will be fenced because the peer has not been seen by the cluster
Aug 31 10:59:37 [30615] node1    pengine:  warning: determine_online_status:   Node node2 is unclean

The server lasts aprox 2 minutes to reboot, so it's normal to haven't been seen after just 6 seconds. But I don't know why the server is rebooted three times:

Aug 31 10:59:31 [30616] node1       crmd:   notice: tengine_stonith_notify:	Peer node2 was terminated (reboot) by node1 for node1: OK (ref=2d7857e7-7e88-482a-812f-b343218974dc) by client crmd.30616
....

After the last message, I only see it stops fencing and start resources:
