Expanding the cluster: adding a storage node in multiple steps (node added, cluster reconfigured, data rebalanced)
Operations are initiated by users; tasks are issued by the system
Storage nodes: migrate a node to another host online, with no interruption of IO
Devices: a removal is temporary, failing a device is permanent
