Hello! We have Pacemaker cluster of two node Active/Backup (OS Centos 6.7), with resources IPaddr2 and ldirectord. Cluster Properties: cluster-infrastructure: cman dc-version: 1.1.11-97629de no-quorum-policy: ignore stonith-enabled: false The cluster has been configured for this documentation: http://clusterlabs.org/quickstart-redhat-6.html Recently, there was a communication failure between cluster nodes and the behavior was like this:
- During a network failure, each server has become the Master. - After the restoration of the network, one node killing services of Pacemaker on the second node. - The second node was not available for the cluster, but all resources remain active (Ldirectord,ipvs,ip address). That is, both nodes continue to be active. We decided to create a test stand and play the situation, but with current version of Pacemaker in CentOS repos, сluster behaves differently: - During a network failure, each server has become the Master. - After the restoration of the network, all resources are stopped. - Then the resources are run only on one node. - This behavior seems to be more logical. Current Cluster Properties on test stand: cluster-infrastructure: cman dc-version: 1.1.14-8.el6-70404b0 have-watchdog: false no-quorum-policy: ignore stonith-enabled: false Changed the behavior of the cluster in the new version or accident is not fully emulated? Thank you. Kind regards, Vladimir Pavlov
