    Description

      If you have a group of mongod nodes that have been started but haven't yet had rs.initiate() run on them, then try to add those nodes as a a replica set shard, you just get back a socket exception with no information about the true nature of the problem.

      Example:

      mongos> sh.addShard("rs_shard6/shard6-ovh-01.edtd.net:27017,shard6-ovh-02.edtd.net:27017")
      {
      	"ok" : 0,
      	"errmsg" : "couldn't connect to new shard socket exception [CONNECT_ERROR] for rs_shard6/shard6-ovh-01.edtd.net:27017,shard6-ovh-02.edtd.net:27017"
      }
      

      From the logs:
