      $ mongodump

      > db.coll.drop()

      > use test > db.dropDatabase() > db.createCollection("coll") $ mongodump > db.coll.drop() $ mongorestore

    Description

      The db.createCollection() helper has some optional collection options which get set to undefined if they are not provided. This causes mongodump to output undefined elements which can cause mongorestore to fail.

      The documents have the form:

      { "options" : { "create" : "coll", "capped" :

      { "$undefined" : true }

      , "size" :

      { "$undefined" : true }

      }, "indexes" : [ { "v" : 1, "key" :

      { "_id" : 1 }

      , "ns" : "test.coll", "name" : "id" } ] }
