问题描述

1.添加数据时，报错，原因是，一旦在存储超过95％的磁盘中的节点上分配了一个或多个分片的任何索引， 该索引将被强制进入只读模式

ClusterBlockException[blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
]at org.elasticsearch.cluster.block.ClusterBlocks.indexBlockedException(ClusterBlocks.java:183)at org.elasticsearch.action.support.replication.TransportReplicationAction$ReroutePhase.handleBlockExceptions(TransportReplicationAction.java:806)at org.elasticsearch.action.support.replication.TransportReplicationAction$ReroutePhase.doRun(TransportReplicationAction.java:706)at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37)at org.elasticsearch.action.support.replication.TransportReplicationAction.doExecute(TransportReplicationAction.java:170)at org.elasticsearch.action.support.replication.TransportReplicationAction.doExecute(TransportReplicationAction.java:98)at org.elasticsearch.action.support.TransportAction$RequestFilterChain.proceed(TransportAction.java:167)at org.elasticsearch.xpack.security.action.filter.SecurityActionFilter.apply(SecurityActionFilter.java:128

2.解决方法

PUT _settings
{"index": {"blocks": {"read_only_allow_delete": "false"}}
}
