We are using following ILM policy:

```auto
    "policy": {
        "phases": {
          "hot": {
            "min_age": "0ms",
            "actions": {
              "rollover": {
                "max_age": "1d",
                "max_docs": 60000000
              },
              "set_priority": {
                "priority": 100
              }
            }
          },
          "warm": {
            "actions": {
              "allocate": {
                "require": {
                  "data": "warm"
                }
              },
              "forcemerge": {
                "max_num_segments": 1
              },
              "set_priority": {
                "priority": 50
              },
              "shrink": {
                "number_of_shards": 1
              }
            }
          }
        }
      }
    }

```

On rollover the cluster goes into yellow state, I guess during the force merge, when it creates the replica after merging the index into one shard. Is this a expected behaviour, with this kind of setup?
