solr6.0伪集群搭建collection创建失败

大家好，我在自己的机子上搭建了一个solr伪集群环境，启动都成功了，但在创建时遇到问题。

创建collection指令：
solr-6.0.0-1/bin/solr create_collection -c  search -d solr-6.0.0-1/solrhome/conf/files/ -shards 3 -replicationFactor 2

错误代码：
Connecting to ZooKeeper at localhost:2181,localhost:2182,localhost:2183 ...
Re-using existing configuration directory search

Creating new collection 'search' using command:
http://localhost:8984/solr/admin/collections?action=CREATE&name=search&numShards=3&replicationFactor=2&maxShardsPerNode=2&collection.configName=search


ERROR: Failed to create collection 'search' due to: Could not fully create collection: search
麻烦大家帮忙看看可能是什么问题，谢谢。
