shutdown

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

The command has the following syntax:

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

The command takes these fields:

Field
Description
shutdown

Specify 1.

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.

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:

  1. Attempts to step down to a secondary.

    If the step down fails and a:

  2. Enters the quiesce period.

  3. Ends any remaining database operations.

  4. 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:

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:

A comment can be any valid BSON type (string, integer, object, array, etc).

New in version 4.4.

Tip

See also:

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 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.

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:

  1. Attempts to step down to a secondary.

    If the step down fails and a:

  2. Enters the quiesce period.

  3. Ends any remaining database operations.

  4. 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:

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.

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.

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