Wildfly cluster failover test not working as expected on windows OS, when network is disabled on a VM(Node) or by shutting down the VM (Node). ---------------------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-6762 URL: https://issues.jboss.org/browse/WFLY-6762 Project: WildFly Issue Type: Quality Risk Components: Clustering Affects Versions: 8.2.0.Final Reporter: Preeta Kuruvilla Assignee: Paul Ferraro Priority: Blocker In your mail related to WFLY-6749 you has said the below :- **The default stack contains the following failure detection protocols: FD_SOCK FD_ALL These protocols are described here: http://www.jgroups.org/manual/index.html#FailureDetection I suspect that your method of simulating a failure - by disabling the network of the host machine is not being detected by FD_SOCK. It will however, be detected by FD_ALL, but only after 1 minute. The heartbeat timeout used by FD_ALL can be manipulated via the timeout property. e.g. <protocol type="FD_ALL" ><property name="timeout">60000</property></protocol> ************************************************************************************************** Thanks for the quick response on WFLY-6749. Based on your suggestion, I had a taken a look at the testing scenarios mentioned in "Table 29. Failure detection behavior" in the link that you provided- http://www.jgroups.org/manual/index.html#FailureDetection. No where its mentioned that disabling a network on a node, is a valid testing scenario in Wildfly cluster. The Failover is working properly when the network on a node is disabled on a weblogic cluster for our application. However it doesn't work and it hampers the application functionality on Wildfly cluster when we try to disable the network on a node in Wildfly cluster. However as I said earlier, the failover on wildfly cluster works when we stop a node from admin console or give Ctrl + C to stop the services on a node. Would like to get a confirmation from you that disabling the network on a node is not the valid failover testing scenario for wildfly cluster. Also we tried to test the same failover scenario by Shutting down/power off a VM (node) in a wildfly cluster. It did not work for Windows Environment although it worked for linux environment. Note: we are using Windows 2012 environment.
