ES自动创建索引的问题

ES集群共5个data-node节点，若索引设置的分片数为5，number_of_replaces为1。我手动停掉一个data-node节点后，集群会变为red。当我重启关掉的data-node节点后，查看集群状态，集群会出现一些pending_tasks任务，任务中出现了一个优先级为URGENT的任务---creat_index。而这个创建的索引为类似0a580aa00ffb的索引（这样命名的索引应该不是我建的），之后pending_tasks出现了delete_index的任务（删除了类似0a580aa00ffb的索引），之后出现了put-mapping的任务（查看master日志，也是在put-mapping类似0a580aa00ffb的索引）。
我想问的是：类似0a580aa00ffb的索引为什么会创建？有什么作用？

    红框中的索引断定不是我建的，并且，我删除后，还是会自动新建这些索引

    你是不是在创建索引的时候，有节点下线，我之前遇到的问题是在三节点的es集群，执行创建索引操作，然后，在创建索引的过程中，让主节点和其中一个master_eligible节点下线，再重新启动集群，集群无法启动，日志如下：
    我的数据时分磁盘存储，然后，就报其他磁盘数据没有写入，集群无法启动，es的版本是5.x，6.x也尝试过，创建索引过程中，让集群下线，而没有下线的节点几个盘正常写入，而下线的节点，就是报这个异常，不知道是否和你的一样

    索引里面的数据拉出来看看，不可能无缘无故有新索引产生的。

    这些自动创建的索引可能跟action.auto_create_index有关，有没有设置为false，我遇到过自动创建索引，生成的索引名称也很奇怪，好像是各种文件名。
