Changed in version 5.0.

shutdown: The shutdown command cleans up all database resources and then terminates the process. You must issue the shutdown command against the admin database.

Syntax

The command has the following syntax:

db.adminCommand(
   {
     shutdown: 1,
     force: <boolean>
     timeoutSecs: <int>,
     comment: <any>
   }
)

Command Fields

The command takes these fields:

Field	Description
shutdown	Specify `1`.
force	Optional. Specify `true` to force the `mongod` or `mongos` to shut down. Force shutdown interrupts any ongoing operations on the `mongod` or `mongos` and may result in unexpected behavior.
timeoutSecs	Optional. Starting in MongoDB 5.0, `mongod` and `mongos` enter a quiesce period to allow any ongoing database operations to complete before shutting down. If a `mongod` primary receives a shut down request, the primary: Attempts to step down to a secondary. If the step down fails and a: `shutdown` or `db.shutdownServer()` command was run, `mongod` only continues the shut down steps if the force field is true, or a `SIGTERM` signal was sent to `mongod`, `mongod` always continues the shut down steps. Enters the quiesce period. Ends any remaining database operations. Shuts down. For a `mongod` secondary or `mongos` shut down request, the quiesce period is entered after a shut down was requested. The quiesce period is specified by the: timeoutSecs field if a `shutdown` or `db.shutdownServer()` command was run, or `shutdownTimeoutMillisForSignaledShutdown` server parameter if a `SIGTERM` signal was sent to `mongod`, or `mongosShutdownTimeoutMillisForSignaledShutdown` server parameter if a `SIGTERM` signal was sent to `mongos`. Clients cannot open new connections to a `mongod` or `mongos` that is shutting down. timeoutSecs specifies a time period in seconds. The default is: 15 seconds starting in MongoDB 5.0. 10 seconds in MongoDB versions earlier than 5.0. `mongod` uses timeoutSecs as follows: If the current node is the primary node of a replica set, `mongod` waits for a period of up to the number of seconds specified by the timeoutSecs field for an electable node to catch up before stepping down the primary node. For details about the catch up time, see replication lag. If the current node is in the `SECONDARY` state after stepping down from being the primary, any remaining time specified in timeoutSecs is used for a quiesce period, which allows existing operations to complete. New operations are sent to other replica set nodes. Starting in MongoDB 5.0, `mongos` uses timeoutSecs as a quiesce period, which allows existing operations to complete. New operations are sent to other `mongos` nodes. In MongoDB versions earlier than 5.0, `mongos` shuts down immediately and does not use timeoutSecs. In MongoDB 4.4 and earlier, for a `mongod` primary, timeoutSecs is the number of seconds the primary should wait for a secondary to catch up. If no secondaries catch up within the specified time, the command fails. Defaults to `10` seconds.
`comment`	Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations: mongod log messages, in the `attr.command.cursor.comment` field. Database profiler output, in the `command.comment` field. `currentOp` output, in the `command.comment` field. A comment can be any valid BSON type (string, integer, object, array, etc). New in version 4.4.

Tip

Behavior

For a mongod started with Authentication, you must run shutdown over an authenticated connection. See Access Control for more information.

For a mongod started without Authentication, you must run shutdown from a client connected to the localhost interface. For example, run mongosh with the --host "127.0.0.1" option on the same host machine as the mongod.

`shutdown` on Replica Set Members

shutdown fails if the replica set member is running certain operations such as index builds. You can specify force: true to force the member to interrupt those operations and shut down.

Shutting Down the Replica Set Primary, Secondary, or `mongos`

Starting in MongoDB 5.0, mongod and mongos enter a quiesce period to allow any ongoing database operations to complete before shutting down.

If a mongod primary receives a shut down request, the primary:

Attempts to step down to a secondary.
If the step down fails and a:
- shutdown or db.shutdownServer() command was run, mongod only continues the shut down steps if the force field is true, or a
- SIGTERM signal was sent to mongod, mongod always continues the shut down steps.
Enters the quiesce period.
Ends any remaining database operations.
Shuts down.

For a mongod secondary or mongos shut down request, the quiesce period is entered after a shut down was requested.

The quiesce period is specified by the:

timeoutSecs field if a shutdown or db.shutdownServer() command was run, or
shutdownTimeoutMillisForSignaledShutdown server parameter if a SIGTERM signal was sent to mongod, or
mongosShutdownTimeoutMillisForSignaledShutdown server parameter if a SIGTERM signal was sent to mongos.

Clients cannot open new connections to a mongod or mongos that is shutting down.

timeoutSecs specifies a time period in seconds. The default is:

15 seconds starting in MongoDB 5.0.
10 seconds in MongoDB versions earlier than 5.0.

mongod uses timeoutSecs as follows:

If the current node is the primary node of a replica set, mongod waits for a period of up to the number of seconds specified by the timeoutSecs field for an electable node to catch up before stepping down the primary node. For details about the catch up time, see replication lag.
If the current node is in the SECONDARY state after stepping down from being the primary, any remaining time specified in timeoutSecs is used for a quiesce period, which allows existing operations to complete. New operations are sent to other replica set nodes.

Starting in MongoDB 5.0, mongos uses timeoutSecs as a quiesce period, which allows existing operations to complete. New operations are sent to other mongos nodes. In MongoDB versions earlier than 5.0, mongos shuts down immediately and does not use timeoutSecs.

In MongoDB 4.4 and earlier, if running shutdown against the replica set primary, the operation implicitly uses replSetStepDown to step down the primary before shutting down the mongod. If no secondary in the replica set can catch up to the primary within 10 seconds, the shutdown operation fails. You can issue shutdown with force: true to shut down the primary even if the step down fails.

Warning

Force shutdown of the primary can result in the rollback of any writes not yet replicated to a secondary.

Access Control

To run shutdown on a mongod enforcing Authentication, the authenticated user must have the shutdown privilege. For example, a user with the built-in role hostManager has the appropriate permissions.

Examples

Shut down a `mongod`

db.adminCommand({ "shutdown" : 1 })

Force Shut Down a `mongod`

db.adminCommand({ "shutdown" : 1, "force" : true })

Shut Down a Primary `mongod` With Longer Timeout

db.adminCommand({ "shutdown" : 1, timeoutSecs: 60 })
