Cleaning up red Shards

Elastic Stack Elasticsearch
1

Hi everyone,

say you have 100-200 index's where one of the shards, replica and primary
have gotten corrupted. Lets just say they are completely bonked.

Someone must have a simply query to identify which index's these are and
how to mass delete them all since they have entered an unrecoverable state.

Regards

John

Check out the cat APIs for, there are end points for indexes and shards
that will give you this info.

Hey mate, sorry solved this in the irc channel.

For future reference I created the following command to delete all red
index's.

curl -s localhost:9200/_cat/indices 2>&1 | grep ^red | awk '{print $2}' |
while read red; do curl -XDELETE 'http://localhost:9200/$red'; done

Regards

John
