ROLL CLUSTER

The following command can be used to roll a given cluster. Rolling a cluster will gradually replace the instances of the cluster with new instances. This is a useful action to apply certain cluster configuration changes immediately.

Syntax

ROLL CLUSTER <cluster_name> [NO_GRACE_PERIOD = {TRUE | FALSE}]

Parameters

• NO_GRACE_PERIOD - If this option is TRUE the cluster's instances will all be shut down at once with no grace period. This is in contrast to the gradual roll of instances applied by default. Using this option can cause some downtime of the web UI if done on the API cluster.
