Graceful migration of resources when the *pacemaker_remote* service is stopped on an active Pacemaker Remote node
If the *pacemaker_remote* service is stopped on an active Pacemaker Remote node, the cluster will gracefully migrate resources off the node before stopping the node. Previously, Pacemaker Remote nodes were fenced when the service was stopped (including by commands such as "yum update"), unless the node was first explicitly taken out of the cluster. Software upgrades and other routine maintenance procedures are now much easier to perform on Pacemaker Remote nodes.
Note: All nodes in the cluster must be upgraded to a version supporting this feature before it can be used on any node.
