curl -XGET http://172.20.9.76:9200/_cluster/health\?pretty
{
"cluster_name" : "elasticsearch_MYBOOKING",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 2,
"number_of_data_nodes" : 2,
"active_primary_shards" : 85,
"active_shards" : 85,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 2
}2）找到未分片的索引
curl -s "http://172.20.9.76:9200/_cat/shards" | grep UNASSIGNED
3）执行reroute
curl -XPOST '172.20.9.76:9200/_cluster/reroute' -d '{
"commands" : [ {
"allocate" : {
"index" : "logstash-2018.07.20",
"shard" : 3,
"node" : "_0WmGRqVQ4WlQuEncqvOBw",
"allow_primary" : true
}
}4）实在不行就删除该索引
curl -XDELETE http://172.20.9.76:9200/logstash-2018.07.20
