15.4 Cluster Resource Is Not Accessible After a Network Service Restart

If you restart the network services, cluster resource IP addresses will get removed from the network interfaces. As a result, the cluster resources will not be accessible through those IP addresses. Network service restart can happen as part of LAN settings reconfiguration through YaST or through the rcnetwork restart command. In order to recover from this state, follow the steps mentioned below:

  1. Run the cluster leave command to remove the node from the cluster. This will cause the cluster resources running on this node migrate to another node in the cluster.

  2. Run the cluster join command to rejoin the node to the cluster.

  3. (Optional) You can also manually migrate the resources back to this node by running the cluster migrate command.
