Hello again, Yes both are possible. What matters in that case is that you have two bricks to keep the stripe count of two. Note that if you split your node into two bricks and stripe over them, you will share the bandwidth between those bricks, and they will likely be of different size than the other brick stripes. From time to time you'll probably have to rebalance.
