st_volume_move_node
For each node that you want to move, you must specify a destination node. The 'src_nodes' and 'dest_nodes' must be of equal size. The nodes to be moved can be online or offline, the destination nodes have to be online.
Moving a node may be denied in any of the following cases: - one or more segments on the source node have a snapshot map, - one or more segments on the source node have a redundancy segment on the destination node, - the source node is used for recovering another node and no other suitable node is available or - a segment on the source node is an unlock condition (if it was moved, the data in that address range would be lost).
