Chapter 24. Clustering

Pacemaker Remote may shut down, even if its connection to the cluster is unmanaged

Previously, if a Pacemaker Remote connection was unmanaged, the Pacemaker Remote daemon would never receive a shutdown acknowledgment from the cluster. As a result, Pacemaker Remote would be unable to shut down. With this fix, if a Pacemaker Remote connection is unmanaged, the cluster now immediately sends a shutdown acknowledgement to Pacemaker Remote nodes that request shutdown, rather than wait for resources to stop. As a result, Pacemaker Remote may shut down, even if its connection to the cluster is unmanaged. (BZ#1388489)

pcs now validates the name and the host of a remote and guest node

Previously, the pcs command did not validate whether the name or the host of a remote or guest node conflicted with a resource ID or with a cluster node, a situation that would cause the cluster not to work correctly. With this fix, validation has been added to the relevant commands and pcs does not allow a user to configure a cluster with a conflicting name or conflicting host of a remote or guest node.
