Release Notes for Scyld ClusterWare:

  • Starting with this release, ClusterWare no longer supports RHEL 7 and CentOS 7 (el7) for head nodes. Images for those operating systems will continue to work and be supported temporarily in this and later releases, but head nodes must be el8 or el9, including RHEL, Rocky, or CentOS Stream operating systems.

  • This release expands the use of the cluster-wide certificate authority shared among the head nodes. ClusterWare will now use encrypted communications when communicating with the etcd database or between head nodes. Additionally, both encrypted and unencrypted channels are supported for MQTT using either the native protocol or websockets.

  • This release adds support for controlling switches running the SONiC operating system. Related changes have also improved support for Ubuntu-based images on compute nodes. Future releases will expand switch control functionality to cover more switching hardware and provide switch configurations via ZTP.

Important

Updating from 12.0.1 and earlier to 12.1.0 requires reconfiguration of the Influx/Telegraf monitoring stack. The following command can be used to update the necessary config files: /opt/scyld/clusterware/bin/influx_grafana_setup --tele-env, followed by systemctl restart telegraf. All data will persist through the upgrade.
