Issue
- Upgrading from Elasticsearch 7.9.0 to 7.17.0, index status is YELLOW
- The UNASSIGNED shard can be seen with the following command
$ curl search:9200/_cat/shards
.ds-.logs-deprecation.elasticsearch-default-2022.10.13-000001 0 p STARTED 10.0.0.88 search-0
.ds-.logs-deprecation.elasticsearch-default-2022.10.13-000001 0 r UNASSIGNED
Environment
- Liferay PaaS (DXP 7.3)
solution
- One replica shard is not allocated (UNASSIGNED) for the index for Elasticsearch, so the node itself has YELLOW status
- Delete the concerned replica shard with the following command
curl -XPUT search:9200/.ds-.logs-deprecation.elasticsearch-default-2022.10.13-000001/_settings -H 'Content-Type: application/json' -d'{ "number_of_replicas":0 }'
