Hey,

Backstory:  
We're using ELK to sift through logs.  
I copied (filesystem) the elastisearch data directory from a backup on a new server where I launched a container form the same image that created the data, which runs `elasticsearch 1.7.1`.

When querying elasticsearch manually everything seems to be fine:

```
$ curl -XGET 'http://localhost:9200/logstash-2015.08.31/_count?pretty' -d '{
"query": { "match_all" :{}}}'
{
  "count" : 3186523,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  }
}

```

Replacing `_count` with `_search` in that query also works fine.

Now on to Kibana `4.1.2`:

When I try to `Discover` logs I get the error `Courier Fetch: 5 of 5 shards failed` and Elasticsearch produces some errors:

```
[2015-09-30 13:31:03,812][DEBUG][action.search.type] [Marc Spector] [636] Failed to execute fetch phase

```

Full error log: [http://ix.io/l6c](http://ix.io/l6c)

Now why am I posting this here under kibana and not under elasticsearch you might ask...

The thing is: `Visualize` (and `Dashboard`) continue to work and do show me the requested data without any ES errors....

Where would I start looking to solve this issue?

Thank you for your time,  
Jeroen

Hey,

I managed to "fix" this by pushing new (dummy) data in to the indices for which I got the error.

I have no idea what happened though. Just playing around.
