Hello all,

I am trying to restore a snapshot from a 5 node v6.8 to a single v7.9 host.  
When restoring the snapshot it finishes almost instantly. So no data was imported as its 166gb snapshot. My status goes red and shows 5 unassigned shards and that's it. How can I get this to restore?

Anything in logs?

I do not see anything in logs. Using the kibana console I see these:  
allocate\_explanation" : "cannot allocate because allocation is not permitted to any of the nodes",  
"explanation" : "primary shard for this replica is not yet active"

honestly I have tried a ton I have found online, these are the latest two from my notes.

POST /\_snapshot/my\_backup/my\_snapshot20201101/\_restore

{  
"indices": "data\_stream\_1,index\_1,index\_2",  
"ignore\_unavailable": true,  
"include\_global\_state": false,  
"rename\_pattern": "index\_(.+)",  
"rename\_replacement": "restored\_index\_$1",  
"include\_aliases": false  
}

and

curl --user elastic -XPUT "localhost:9200/my\_snapshot20201101/\_settings?pretty" -H 'Content-Type: application/json' -d' { "number\_of\_replicas": 0 }'

What is the output of:

```auto
GET /
GET /_cat/nodes?v
GET /_cat/health?v
GET /_cat/indices?v

```

If some outputs are too big, please share them on [gist.github.com](http://gist.github.com) and link them here.

Could you run that on both clusters?

Please format your code, logs or configuration files using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.

That's the expected behaviour, a `200 OK` just means the restore has been initialised. You can use the [index recovery API](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-recovery.html) to monitor its progress, and [cluster allocation explain](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-allocation-explain.html) to determine why any shards aren't allocated.

> [@elkdummy](#):
>

Replicas cannot be allocated before the primary. You need to determine why the primary isn't active.

Looks like after sitting there for a while this error is now also showing  
All errors posted are from using "GET /\_cluster/allocation/explain"

"explanation" : "shard has failed to be restored from the snapshot [my\_backup:my\_snapshot20201101/cztjiMTZQ\_OlZSGDADFqVg] because of [restore\_source[my\_backup/my\_snapshot20201101]] - manually close or delete the index [my\_snapshot20201101] in order to retry to restore the snapshot again or use the reroute API to force the allocation of an empty primary shard"

That is the thing, the recovery API shows nothing. All it ever shows is { }. Please see my reply about new error showing using the explain command.

I don't think this is the pertinent part of the response from `GET /_cluster/allocation/explain`. Please share the whole output.

Thank you for your reply and help. I also added one reply with more info of an error about forcing a primary shard.

The primary cluster is custom with no web. It's all command line and I would not be able to post much about it. I know this might make things difficult, but if there is something in particular that is a must I can get it out and modify what cannot be posted publicly.

The reply did not go to you, so I tried to remove it and reply but error. Hopefully this works.

How would I tell it to ignore, change, fix that? I thought it ignored this if the setting do not use global.

That's not a global setting so `include_global_state` has no effect. You're looking for `ignore_index_settings` instead -- see [the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/restore-snapshot-api.html#restore-snapshot-api-request-body) for further details.

Is this correct? It made no change to the error.

```auto

No, you need to list the settings to ignore under `ignore_index_settings` not their values. So `index.routing.allocation.require.box_type`.

I tried the following with no luck. If this is not correct would you be willing to provide the proper code for me?

```auto

"index.routing.allocation.require.box_type": "warm"
