在es document中，它引入了If we restart Node 1,If Node 1 still has copies of the old shards, it will try to reuse them, copying over from the primary shard only the files that have changed in the meantime。
所以我做了一个实验。
以下是我的群集中的5个节点，主分片1保存在节点1中，副本分片1保存在节点2中。当我重新启动节点时1和节点2，主要分片1的状态变为UNASSIGNED，副本分片1的状态变为{{ 1}}，群集的运行状况也变为UNASSIGNED，运行状况永远不会变为red。群集停止工作，直到我删除旧索引。
这是主日志的一部分。
