validate

The validate command checks the contents of a namespace by scanning a collection’s data and indexes for correctness. The command can be slow, particularly on larger data sets:

{ validate: "users" }

This command will validate the contents of the collection named users. You may also specify one of the following options:

• full: true provides a more thorough scan of the data.

• scandata: false skips the scan of the base collection

  without skipping the scan of the index.

The mongo shell also provides a wrapper:

db.collection.validate();

Use one of the following forms to perform the full collection validation:

db.collection.validate(true)
db.runCommand( { validate: "collection", full: true } )
