ShardMissingCollectionRoutingInfo inconsistency documents contain these fields:

Field	Type	Description
`type`	string	Type of inconsistency document. Returns a value of `ShardMissingCollectionRoutingInfo` for this inconsistency type.
`description`	string	Describes the inconsistency found in the metadata.
`details`	document	Document with additional information on where the inconsistency exists in the database and sharded cluster.
`details.namespace`	string	Indicates the database and collection where the inconsistency exists.
`details.collectionUUID`	UUID	UUID of the collection.

Example

Use the db.adminCommand() method to call the checkMetadataConsistency command:

db.adminCommand( { checkMetadataConsistency: 1 } )

The method returns a cursor with a batch of documents showing the inconsistencies found in the sharding metadata. The example below shows a cursor with a ShardMissingCollectionRoutingInfo inconsistency document:

{
   cursor: {
      id: Long("0"),
      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "ShardMissingCollectionRoutingInfo",
            description: "Shard is missing routing information for the collection",
            details: {
               namespace: "test.authors",
               collectionUUID: new UUID("62ebdb7e-a7bb-4151-a620-49d44cef097f"),
               shard: "shard02"
            }
         }
      ],
   },
   ok: 1
}
