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 CorruptedZoneShardKey
inconsistency document:
{ cursor: { id: Long("0"), ns: "test.$cmd.aggregate", firstBatch: [ { type: "CorruptedZoneShardKey", description: "Found zone with a shard key pattern violation", details: { namespace: "test.authors", collection: { collectionUUID : new UUID("1ad56770-61e2-48e9-83c6-8ecefe73cfc4"), zone : { ns : "test.authors", tag: "64ddd81656be208c6685da21", min: { y: 0 }, max: { x: MaxKey } }, shardKeyPattern: { x: 1 } } } } ], }, ok: 1 }
