rs.remove()¶

Definition定义¶

rs.remove(hostname)¶

Removes the member described by the hostname parameter from the current replica set. This function will disconnect the shell briefly and forces a reconnection as the replica set renegotiates which member will be primary. As a result, the shell will display an error even if this command succeeds.

The rs.remove() method has the following parameter:

Parameter参数	Type类型	Description描述
hostname	string	The hostname of a system in the replica set.

Note

Before running the rs.remove() operation, it is good practice to shut down the replica set member that you are removing.

Behavior行为¶

By default, replica set members wait for 5 minutes before dropping connections to the removed member. In sharded replica sets, you can modify this timeout using the ShardingTaskExecutorPoolHostTimeoutMS server parameter.

db.adminCommand(
  {
    "dropConnections" : 1,
    "hostAndPort" : [
      "<hostname>:<port>"
    ]
  }
)

Replace <hostname> with the hostname of the removed member and <port> with the port the mongod listened on.
