Due to power failure, a node has failed. And from the time the node has failed it took 5 mins to Auto-failover. The logs from the "ns_server.info.log" is attached. The log file "Failover" only contains the 5 mins of Auto-Failover information in it. Also the Stats from failed node(10.22.64.9) and one other node(10.22.64.12) is attached for more information about the cluster. If need any other information please let me know. i will glad to provide you.
