And the \_`cat/nodes` [page](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-nodes.html) shows the codes.

node.role, r, role, nodeRole  
(Default) Roles of the node. Returned values include c (cold node), d (data node), f (frozen node), h (hot node), i (ingest node), l (machine learning node), m (master-eligible node), r (remote cluster client node), s (content node), t (transform node), v (voting-only node), w (warm node), and - (coordinating node only).
