Hello Elastic Team.  
Fresh and new elasticsearch-7.4.0-1 cluster (3 data nodes data\_type: warm + 3 master/data nodes data\_type: hot).  
What i am trying to implement is hot/warm architecture

- today index kept on HOT (local SSDs)
- later beeing rolledover to warm (SAS)

Using

```auto
       "allocation": {
         "require": {
           "data_type": "hot"
         }
       }
     },

```

in the index template  
and

`cluster.routing.allocation.awareness.attributes: data_type`

in the config - i managed to have the primaries beeing stored only on HOT.  
But replicas beeing reported as Unassigned.

Anyone any advice - please ?

Use shard allocation filtering, not shard allocation awareness.
