elasticsearch：cluster_block_exception TOO_MANY_REQUESTS/12/index 只读/允许删除（api）

Question

我正在运行具有多进程索引的蜘蛛，我想解决这个问题。

我总是收到 TOO_MANY_REQUESTS，是否可以更改配置以允许更大的阈值来处理并发请求？

这是完整的错误

更新： 发现洪水盘水印已超标，但似乎没有超标！

Answer 1

根据你得到的错误信息，你的磁盘已满

flood stage disk watermark [5gb] exceeded on [Z8G4W5UlQYy1HOk0JWGP7w][n1_it][/usr/share/elasticsearch/data/nodes/0] free: 3.8gb[1.6%], all indices on this node will be marked read-only

您需要增加该节点的可用磁盘空间。
