Stop Defragmenting a Sharded Collection
On this page本页内容
Typically, you should use a shard balancing window to specify when the balancer runs instead of manually starting and stopping defragmentation.
To manually stop defragmenting a sharded collection, use the configureCollectionBalancing
command with the defragmentCollection
option set to false
.
About this Task
The procedure in this task uses an example sharded collection named ordersShardedCollection
in a database named test
.
You can use your own sharded collection and database in the procedure.
If you stop defragmenting a collection before defragmentation is complete, the collection is in a partially defragmented state and operates as usual. To resume defragmentation, restart the process.
Before you Begin
- Start defragmenting a sharded collection. For details, see Start Defragmenting a Sharded Collection.
- Connect to

Procedure
Ensure defragmentation stopped
When defragmentation stops, the command output returns ok: 1
:
{
ok: 1,
'$clusterTime': {
clusterTime: Timestamp({ t: 1678834337, i: 1 }),
signature: {
hash: Binary(Buffer.from("0000000000000000000000000000000000000000", "hex"), 0),
keyId: Long("0")
}
},
operationTime: Timestamp({ t: 1678834337, i: 1 })
}
Next Steps
You can start defragmentation again at any time. For details, see Start Defragmenting a Sharded Collection.
