elasticsearch index read-only

搜索引擎報下面錯誤時, 經過排查是因爲存儲空間不足了.

ClusterBlockException[blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
]
	at org.elasticsearch.cluster.block.ClusterBlocks.indicesBlockedException(ClusterBlocks.java:204)
	at org.elasticsearch.action.admin.indices.mapping.put.TransportPutMappingAction.checkBlock(TransportPutMappingAction.java:75)
	at org.elasticsearch.action.admin.indices.mapping.put.TransportPutMappingAction.checkBlock(TransportPutMappingAction.java:44)

修改配置文件指定索引目錄, 找個存儲空間充足的盤
config/elasticsearch.yml

path.data: F:/es_data
#
# Path to log files:
#
path.logs: F:/es_data/logs

然後執行解鎖操作

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
