How to move indexs from hot node to warm node?

[cucukaka]

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
opensearch 2.8.0

Describe the issue:
First, Nodes setted attributes for nodes like this

node.attr.temp: hot
node.attr.temp: warm

this is my real env

Second, apply policy like this

{
    "id": "log-policy",
    "seqNo": 5446,
    "primaryTerm": 1,
    "policy": {
        "policy_id": "og-policy",

            {

                    {
                        "retry": {
                            "count": 3,
                            "backoff": "exponential",
                            "delay": "1m"
                        },
                        "rollover": {

                        }
                    }
                ],
                "transitions": [
                    {
                        "state_name": "warm"
                    }
                ]
            },
            {
                "name": "warm",
                "actions": [],
                "transitions": [
                    {
                        "state_name": "delete",
                        "conditions": {
                            "min_index_age": "45d"
                        }
                    }
                ]
            },
            {
                "name": "delete",
                "actions": [
                    {
                        "retry": {
                            "count": 3,
                            "backoff": "exponential",
                            "delay": "1m"
                        },
                        "delete": {}
                    }
                ],
                "transitions": []
            }
        ],
        "ism_template": [
            {
                "index_patterns": [
                    "log-network*"
                ],
                "priority": 1000,
                "last_updated_time": 1690419598300
            }
        ]
    }
}

so this rollover was successfully applied.
But Node did not move from hot node(os-node2, 3, 4, 5, 6) to warm node(os-node7)
The index in the warm step is still in the hot node, os-node2, 3, 4, and 5.

this is hot state in policy

this is warm state in policy (same node…)

plus, the delete policy also applies well…

how to move index from hot node to warm node using policy???

@cucukaka Your transition in the hot stage is missing conditions.

I added conditions in hot states but nodes in warm states still is in hot nodes(os-node2~6)

@cucukaka You need to add allocation in warm state

{
                "name": "warm",
                "actions": [
                    {
                        "retry": {
                            "count": 3,
                            "backoff": "exponential",
                            "delay": "1m"
                        },
                        "allocation": {
                            "require": {
                                "temp": "warm"
                            },
                            "include": {},
                            "exclude": {},
                            "wait_for": false
                        }
                    },

Thanks !! The setting has been changed, it worked!

Great, but I think this is not the only problem you will face when configuring ISM. For example, I now have the following question ISM shrink issue
