Description
Some users have large collections (> 256gb), which cannot be sharded as per the normal sharding process/methodology.
You have to write a script to read it and insert into the sharded collection. You then need to blow away the old collection and rename the new collection.
The limit is mentioned here but I believe that it should be more explicitly mentioned in the central sharding documentation area along with a process on what can be done.
