Release Notes for Scyld ClusterWare:

  • This release provides most of a scyld-nodectl scp implementation along with image capture capabilities along with additional bug fixes. See the changelog for more details. Release notes for 12.0.0 are included below.

  • Penguin Solutions is excited to announce the next major release of Scyld ClusterWare with the release of ClusterWare 12. This release brings many changes and improvements throughout the product, including the completely rewritten graphical console and a new Grafana monitoring interface. Please see Updating ClusterWare 11 to ClusterWare 12, ClusterWare Graphical Interface (GUI), and Monitoring Graphical Interface for details.

  • While most customers will continue to download RPMs or the installation ISO, for container centric environments the ClusterWare team has packaged the head node into an importable image. Please see Appendix: Using Docker for Head Nodes for details.


Upgrading from ClusterWare 11 to 12 may be more complicated than upgrading from ClusterWare 11 to a newer version of ClusterWare 11. Older clusters using Couchbase as the ClusterWare database must upgrade to the etcd database backend prior to the upgrade, and /etc/yum.repos.d/clusterware.repo may potentially require simple modifications to access the new Penguin Computing ClusterWare 12 repo. Please see Updating ClusterWare 11 to ClusterWare 12 for details.
