es集群重启某节点后，节点上的很多shards unassigned
重启节点只是添加了一些配置(minio做es快照存储的配置，应该和这个没关系，因为已经在其他节点上操作过，没出问题）。
集群allocation和rebalance都设置了all
explain如下：
集群allocation和rebalance都设置了all
explain如下：
默认节点磁盘使用率超过85%不允许分配副本，可以看下节点磁盘使用率
尝试过调大这个参数到95%不行，应该不是这个问题，如果是这个问题explain会直接报磁盘空间不足了
那可能就是总shard数大于节点数了，GET _cat/shards?h=index,shard,prirep,state,unassigned.reason 确认下
都是UNASSIGNED NODE_LEFT
应该也不是这个问题，我们集群data节点有22个，分片数最多的才11个分片
分片还有一个副本 那就是22个分片，宕了一个节点，分片就没地方放了。
是重启了B1节点吗 看图里面B1节点没有分配任何分片呢。
是的。 我看B1上数据都在，但就是不分配，奇怪啊
那就是有问题 ，集群认为它离开了 ，所以报错分片无法分配。 具体为什么不分配可以看B1节点的es.log

b1和master的日志都看过，好像也没啥异常的提示

这不就是异常么，提示过期，就没法加入集群。
License Expired - #12 by TimV - Elasticsearch - Discuss the Elastic Stack 可以仔细看看这块操作的风险性
这个过期是xpack，这个没影响的，我们集群每个节点都报这个错。
看了半天这讨论的是es呀
