      I am having 3 Servers 3 ReplicaSet and 3 Shards. I have manually deleted database and its recreated using server application. Now in 2 server if I access data it is in sync buy 1 server is working as is own not in sync. Please some one help me.

      Before deleting it was working fine. All the 3 server database were in sync. If I do rs.status() and sh.status() its output looks ok to me if some one can check this It will be appreciated.
