Is it supported to reassign some of the spare data partitions from let's say Node B to Node A in a root-data-data setup? So essentially Node A uses 70% of all data partitions? I know there is a further complication with spares and two partitions from the same disk can't be inside the same raid group. Which also raises an interesting question about ontap knowing which spare to choose in a failure, does it have intelligence to know not to bring in a spare to a raid group if it already has a partition on that disk?

There should be no problem as long as every node has at least one spare partition of every size it requires. ONTAP seems to be quite intelligent in handling spare partitions and disks, to the point where I have seen it automatically "fix" a non-optimal layout by itself: I had a system where disk X had its partition 1 as spare, and disk Y had its partition 2 as spare. ONTAP automatically started replacing the partitions, so that a full disk was freed and used as a spare.
