If you have node 1 with token 0 and a total token range to 10 then… * add node 2 with token 3 and it will only take ownership of the range 0 to 3. Node 1 will own 3 to 0 * add node 3 with token 6 and it will take ownership of the range 3 to 6. Node 1 will now own 6 to 0
Unless you have an urgent need I would one node at a time and let the bootstrap finish.
