I am using v7.5.2, I have 10 nodes, 6 Data nodes having 8 TB of data and there is plenty of space left.

I have an ILM policy to rollover index after a month from Hot to warm.

I restarted a node after minor config change and I have 60-80 unassigned shards.  
I have tried this API to allocate the replica.

POST \_cluster/reroute

```
 "allocate_replica": {
           "index": "prod-2020.04.23-100077",
           "shard": 0,
           "node": "10thnode"
}

```

I get this error constantly, spent whole day to resolve without much help.

{"error":{"root\_cause":[{"type":"remote\_transport\_exception" ...  
...

**[NO(node does not match index setting [index.routing.allocation.require] filters [data:"warm"])]**

...

Please note I have displayed only the "NO".

Any help please?

An unassigned shard means the master can not find any shard copies after the restart[!](https://tellthebell.onl/)

The reason for Unassigned is because of "NODE\_LEFT" not because master didn't find any copies.

I found out from the "\_cat/shards" API.
