    kbcli cluster restart pulsar-cluster --components="pulsar" \
    --ttlSecondsAfterSucceed=30

    • ttlSecondsAfterSucceed describes the time to live of an OpsRequest job after the restarting succeeds.
  2. Validate the restarting.

    Run the command below to check the cluster status to check the restarting status.
