[mongodb]about shard and many collections

Question

My situation is:

1. I have a mongodb cluster with sharding
2. I considered that sharing is effecting for one collection with specified shard key
3. I insert a new collection through mongos

My question is:

Where and why the new collection stored? If one shared is full, should the new collection auto store in another?

Thank you!

我已经解决了；如果您插入一个未分片的集合，它将存储在默认情况下第一个分片的主分片中，如果主分片已满，则新集合将不会存储在另一个分片中。
