This release features the following improvements: Any special configuration is no longer required on the switch due to multicast being disabled by default between storage nodes. Enabling multicast is allowed via SCS CLI after the installation is done. However, a full (non-rolling) reboot of the entire cluster is required after the SCI upgrade. If your organization instead requires rolling reboots to avoid downtime, then please run the following command after SCI has been updated, but before rebooting any Swarm Storage nodes:
scsctl storage config set -d "cip.multicastEnabled=true"
Once this has been run, a rolling reboot may be safely used to upgrade to the new Swarm Storage software.
LimitationsGUI-based upgrade functions well when the cluster is installed using SCI 2.x, with no manual changes in the configuration files (for example, gateway.cfg and elasticsearch.yml). However, this upgrade inherits the changes of SCS, storage, and gateway done through Content Portal and Swarm UI.
