Thanks. The three nodes all have distinct cluster UUIDs:

```nohighlight
  "cluster_uuid" : "Ki2hYWPYTH-XL3Fm6sIKxg",
  "cluster_uuid" : "6CCZsxyYSJylB9P_kujFlA",
  "cluster_uuid" : "sRZoKEEDQZywbRU3qb8L0Q",

```

This is probably because the first time they started up you were not using the config you quote above, and so they each formed a one-node cluster. You cannot merge separate clusters together. Instead you will need to start again from the beginning: wipe their data directories and restart them, and they should form into a single cluster this time.
