The replSetFreeze command prevents a replica set member from seeking election for the specified number of seconds. Use this command in conjunction with the replSetStepDown command to make a different node in the replica set a primary.

The replSetFreeze command uses the following syntax:

{ replSetFreeze: <seconds> }

If you want to unfreeze a replica set member before the specified number of seconds has elapsed, you can issue the command with a seconds value of 0:

{ replSetFreeze: 0 }

Restarting the mongod process also unfreezes a replica set member.

replSetFreeze is an administrative command, and you must issue it against the admin database.
