+
+Assigns one or more nodes to the specified group, moving them from their
+original group (or groups).
+
+By default, this command will refuse to proceed if the move would split
+between groups any instance that was not previously split (a split
+instance is an instance with a mirrored disk template, e.g. DRBD, that
+has the primary and secondary nodes in different node groups). You can
