Performing Graceful Failover

    Graceful failover is initiated via the POST /controller/startGracefulFailover HTTP method and URI.

    HTTP method and URI

    Initiates graceful failover for a specific server node. The server node is specified with the otpNode=[node@hostname] parameter.

    POST /controller/startGracefulFailover
    The failover progress can be tracked just like rebalance. After the data is persisted to disk and replicas are up-to-date, the node is put into the failed over state.


    POST /controller/startGracefulFailover
    Be sure to update any scripts that implement failover.


    Curl request example:

    curl -u Administrator:password -d 'otpNode=ns_1@' \
