我无法弄清楚,为什么会导致这个错误发生.当一个删除数据或索引它工作正常.
什么可能是它的可能的原因.

特别是那部分：
cluster.routing.allocation.disk.watermark.low controls the low
watermark for disk usage. It defaults to 85%,meaning ES will not
allocate new shards to nodes once they have more than 85% disk used.
It can also be set to an absolute byte value (like 500mb) to prevent
ES from allocating shards if less than the configured amount of space
is available.cluster.routing.allocation.disk.watermark.high controls the high watermark. It defaults to 90%,meaning ES will attempt to relocate shards to another node if the node disk usage rises above 90%. It can also be set to an absolute byte value (similar to the low watermark) to relocate shards once less than the configured amount of space is available on the node.
