    Description

      MongoDB documentation says that default chunksize is 64 MB.
      We have setup MongoDB cluster with default chunksize and loaded 350 GB of data. This setup is on linux machines
      Cluster is of 6 shards with a replication factor of 3.
      After the load is completed, we have checked the sharding stats with the db.<collection>.getShardDistribution.
      shard-3 has 30% data with chunksize of 162GB.
      Remaining shards have 10-14% data each with a chunksize varying from 64-96GB.
      Can you please let me know is this a bug in MongoDB version 2.2.1?
      If not, can you please let me know why this behavior of different chunksize in the same cluster???

      regards,
      Santosh
