首先关于这个问题本人已经持续关注很长时间了，先说结果——elasticsearch（ES）不适合不适合不适合使用分布式存储。测试环境当然无所谓！！！

以下是相关资料的链接（持续更新）：

1.https://www.elastic.co/guide/en/elasticsearch/reference/7.3/tune-for-indexing-speed.html#_use_faster_hardware 

Always use local storage, remote filesystems such as NFS or SMB should be avoided.

2.https://discuss.elastic.co/t/elasticsearch-support-for-ceph-storage/195551

As far as I know Elasticsearch does not support ceph storage.

3.https://discuss.elastic.co/t/use-cephfs-as-elasticsearch-data-storage/171324

It is better to store the data on physical hard disks without a distributed filesystem as abstraction.

4.https://discuss.elastic.co/t/java-nio-file-filesystemexception/138160

 OMG. This not supported.

 

如果有任何一个ES官方人员说生产环境中可以使用分布式存储，本人将删除此文。
