    Description

      There are a number of potential issues that can occur if creating a unique index with dropDups on a collection in a rolling fashion in a replica set as documented in http://docs.mongodb.org/manual/tutorial/build-indexes-on-replica-sets/

      We should document that this is not a good way to build a unique index and also document our suggestions for a unique index with dropDups on a replica set.
