Shards both primary and replica shards

Elastic Stack Elasticsearch

Hi

I am having 6 data nodes and 100 of indices. All indices having 1 replica.

Recently, one of my data node have disk failure hence ES crashed on it.

It is strange to see that few indices lost all of both primary and replica shards. How it is possible, Any clue?

Thanks,
Ankita

You can check whether your data of these indices still exist in you "data_path"

No, shards didn't exists on remaining node data_path.
