Restart a Pulsar cluster

You can restart all pods of the cluster. When an exception occurs in a database, you can try to restart it.

note

The pod role may change after the cluster restarts.

Steps

Configure the values of components and ttlSecondsAfterSucceed and run the command below to restart a specified cluster.
```
kbcli cluster restart pulsar-cluster --components="pulsar" \
--ttlSecondsAfterSucceed=30
```
- components describes the component name that needs to be restarted.
- ttlSecondsAfterSucceed describes the time to live of an OpsRequest job after the restarting succeeds.
Validate the restarting.
Run the command below to check the cluster status to check the restarting status.
```
kbcli cluster list pulsar-cluster
>

pulsar-cluster      pulsar               pulsar-2.11    Delete              Running    19m
```
