某天發現項目的kibana網頁莫名其妙訪問不了了
進入linux系統發現kibana進程沒了，於是開始重啟，發現重啟的極其慢
進入控制台，發現索引報了一個錯
Index lifecycle error cluster_block_exception: index [java-error-log-pengye-000011] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];index [java-error-log-pengye-000012] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];index [java-error-log-pengye-000013] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];index [java-error-log-pengye-000014] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
查網上說是 設置 "blocks.read_only_allow_delete":"false" 可以解決
可是我看該索引的這個屬性是false

還有個是與磁盤空間有關，於是df -h查看了下存儲空間
占用94%
查看官方文檔 https://www.elastic.co/guide/en/elasticsearch/reference/current/disk-allocator.html
設置cluster.routing.allocation.disk.watermark.flood_stage ：99%
重啟es，這次啟動只用了幾秒，解決
