Hello everyone,

I am having some trouble using the **reindex API** to change the settings of metricbeat indexes. My idea is to reindex the original indexes to a new index with just a single shard and 0 replicas.

The new index is created without trouble and the reindex is started but after a while I get the error:

> {"type":"search\_context\_missing\_exception","reason":"No search context found for id [592099]"}

I looked at similar issues like this one: [Problem when reindexing large index - #3 by Juris\_Rats](https://discuss.elastic.co/t/problem-when-reindexing-large-index/117421/3) and tried the solution proposed. I reduced the batch size to 100 and then to 10. Both still led to the error.

Some stats:

- ES version: 6.5.4
- Metricbeat index version: 6.1.1
- Size of metricbeat index: 3.5Gb

I would appreciate any suggestions that might lead to understanding this issue.  
Thanks,  
Ivo

**UPDATE** After moving the data directory used by elasticsearch from a nfs volume to local storage this issue disappeared. [Do not use remote-mounted storage, such as NFS or SMB/CIFS. The latency introduced here is antithetical to performance.](https://www.elastic.co/guide/en/elasticsearch/guide/current/indexing-performance.html#_storage)
