Using multi-node Elasticsearch version 7.14  
I am facing an issue while doing reindexing.I want reindex all the indices given below

```auto
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open log-wlb-sysmon-2021.09.29-000014 gh4KHV6xRgSbk33Yk2cxJw 1 0 0 0 208b 208b

```

**How i done this is given below**

**1.**

```auto
PUT %3Clog-wlb-sysmon-%7Bnow%2Fd%7D-000014%3E 
{
"aliases": {
   "log-wlb-sysmon": {
      "is_write_index": false      
   }
 },
 "settings": {
   "index.lifecycle.parse_origination_date":true
   , "refresh_interval": "-1"
   , "number_of_replicas": 0
 }
}

```

**2.**

```auto
POST _aliases
{
  "actions": [
    {
      "add": {
        "index": "log-wlb-sysmon-2021.09.23-000019",
        "alias": "log-wlb-sysmon",
        "is_write_index": false
      }
    }, {
      "add": {
        "index": "log-wlb-sysmon-2021.09.29-000014",
        "alias": "log-wlb-sysmon",
        "is_write_index": true
      }
    }
  ]
}

```

**3.**

```auto
POST _reindex?max_docs=87312747&wait_for_completion=false
{
  "conflicts": "proceed"
  , "source": {
    "index": "log-wlb-sysmon-2021.08.08-000014"
    , "size": 5000
    
  }
  , "dest": {
    "index": "log-wlb-sysmon-2021.09.29-000014"
  }
}

```

I dont know why it is copying.The index size is 100gb.  
i get the task id... but it's not shown in `GET /_task` API

To know the reason why it stopped.Run the following query  
`GET /_tasks/task_id`  
The task\_id is the id which we got in

> `POST _reindex?max_docs=87312747&wait_for_completion=false`
