我启动了一个新的elasticsearch集群并添加了一个新索引，然后我将其关闭 . 当我尝试再次启动它时，不再有活动的分片 . 所有分片都变为非活动状态且未分配 . 我使用下面的索引设置：
"settings": {
"number_of_shards": 32,
"number_of_replicas": 3
}
这是 Health 输出：
{
"cluster_name" : "sailcraft",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 0,
"active_shards" : 0,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 128,
"number_of_pending_tasks" : 0
}
这是same problem which has been marked solved . 但我不是解决方案 .
编辑：
这是同样的问题，但我认为该帖子没有得到正确的答案 . 它说如果我们有2个以上的副本分片，我们还需要2个节点 . 我阅读了所有相关文档，并没有任何此类限制 .
EDIT2： Solution: he setting index.recovery.initial_shards provides the following: Basically, when using a local gateway, a "shard" will be recovered once a quorum of its copies are found among the nodes in the cluster. Lets take N shard, with 1 replica (2 copies for each shard). The default (quorum) means that once a singe copy of a shard is found, it will be recovered. If you have 2 replicas (3 copies), it will only recover that shard once 2 copies are found. You can set this setting, in case you lost a large number of nodes, and quorum is a too strict setting. You can actually set it on a "live" index (which is in a "red" state, obviously, because not all shards are recovered).

这是the documentation提到这个 . 的确，那里是's not evident, but it'：
如果您确实希望节点运行，请在
elasticsearch.yml文件中设置index.recovery.initial_shards: 1.
