WARNING: Not all replicas will be on distinct nodes

I have a 6 node cluster (now 7) with ring size 128. On adding the most recent node I got the WARNING: Not all replicas will be on distinct nodes. After the initial plan I ran the following sequence many times, but always got the same plan output: sudo riak-admin cluster clear && \ sleep 10 && \ su

According to the docs “Running [riak-admin cluster clear] will also stop the current node in addition to clearing any staged changes. Is there a way to clear the current cluster plan without stopping the current node? Even better (
