I'm looking for guidance on what my options are when I have a corrupt index. I found this out when trying to snapshot and it failed due to a corrupt index. For more Info: [https://discuss.elastic.co/t/understanding-index-shard-snapshot-failed-exception/159572/5](https://discuss.elastic.co/t/understanding-index-shard-snapshot-failed-exception/159572/5) I don't know how to tell if it's a replica or primary so the only thing I know right now is the name of the corrupted index. Also I am not seeing anything standout when I do `GET /INDEX/_stats` It seems a lot of information on corrupt indices seems to be on older ES versions. (I'm on 6.1) So before I follow one of those guides, I am just wondering what/where is the latest information and guidance to resolve this issue? ---

An update to this: I figured out that the corrupted shard id is 0 just from looking closer at the snapshot error. Then afterwards doing: > GET \_cat/shards/winlog-2018.09.05 I get: > INDEX-2018.09.05 0 r STARTED 71460755 36.7gb IP.ADDRESS NODE-master-3 > INDEX-2018.09.05 0 p STARTED 71460755 36.7gb IP.ADDRESS NODE-master-2 I'm assuming the r and p stand for replica and primary. I want to delete the primary in hopes that maybe only that is corrupt. Can someone point me to the correct api for this? ---
