There are two routes for upgrading cluster nodes:

  • Run /usr/share/cb/cbcluster start on the primary node after it has been upgraded. If there are no RPMNEW files on any cluster nodes (indicating modified configuration files), this action upgrades all cluster nodes. If there are new RPMNEW files, cbcluster start will stop and prompt you to manually upgrade the nodes.
  • Upgrading each cluster node manually with cbupgrade . You must do this in any case when there are new RPMNEW files.
Important: If an RPMNEW file is encountered on a node during upgrade, you must reconcile the current configuration files on the node with the new configuration information, and you must remove the RPMNEW file from that node, before cbcluster start can complete successfully.

To upgrade cluster nodes:

  1. Login to the primary node and stop the cluster: 
    /usr/share/cb/cbcluster stop
  2. After the cluster is completely stopped, restart it: 
    /usr/share/cb/cbcluster start

    If there are no RPMNEW files, the cluster nodes are upgraded without further steps. If there are RPMNEW files, you must upgrade each node manually.
