This setting controls the use of multicast for Swarm Storage node intercommunication. Prior to The multicast was mandatory before Swarm v15.0, multicast was required. For clusters already using multicast, it is advised to continue using it as changing the setting value requires a full, non-rolling cluster reboot. New installations may require a special network configuration to support multicast. Therefore, do not use multicast for new installations. If not sure about enabling multicast, contact DataCore Support.

WarningIf you are deploying an SCS with an existing storage cluster, this group value MUST be the same as the cluster.name value of the existing storage cluster. The failure causes an initialization error for the cluster on boot-up (the Persistent Settings Stream stores the cluster.name and does not match the cluster name stored in SCS) and requires resetting and re-initializing the SCS. https://perifery.atlassian.net/wiki/spaces/public/pages/1223491694/SCS+CLI+Commands#scsctl-system-reset |

The following setting(s) require a default value:
disk.volumes [type: str] (Required. Specifies the volume storage devices for Swarm to use. Valid entries: all, or a space-separated list of Linux volume identifiers, such as /dev/sda, /dev/sdb. all (recommended) is required for hot plugging and lets Swarm to use all volumes larger than disk.minGB. If a node is shut down longer than disk.obsoleteTimeout, all of its volumes are stale and cannot be used unless you force a volume remount by adding the :k (keep) policy option modifier. To specify the size, add a modifier with units: vols1:100m vols2:250g.):
all
