我的集群状态为绿色，重启服务后，一个分片仍为“未分配”，状态变为黄色。我有 2 台机器，设置了 5 个分片和 1 个副本集。我使用的是默认配置，多播关闭，单播启用。我使用以下方法进行了重新路由
for shard in $(curl -XGET http://localhost:9201/_cat/shards | grep UNASSIGNED | awk '{print $2}'); do
echo "processing $shard"
curl -XPOST 'localhost:9201/_cluster/reroute' -d '{
"commands" : [ {
"allocate" : {
"index" : "wall",
"shard" : '$shard',
"node" : "node1",
"allow_primary" : false
}
}
]
}'
sleep 5
done
输出如下

但第 0 个分片仍未分配且状态为黄色。

如果您查看日志，您可能会注意到一个问题，例如磁盘空间不足。
您可以将该索引的副本数减少为 0，然后再减少回 1。
另一件很棒的事情是调整复制速度，因为默认情况下它相当慢。
