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.

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.):
