6.14.1. Cluster Configuration Version

A cluster configuration file includes a cluster configuration version value. The configuration version value is set to 1 by default when you create a cluster configuration file and it is automatically incremented each time you modify your cluster configuration. However, if you need to set it to another value, you can specify it with the following command:
ccs -h host --setversion n
You can get the current configuration version value on an existing cluster configuration file with the following command:
ccs -h host --getversion
To increment the current configuration version value by 1 in the cluster configuration file on every node in the cluster, execute the following command:
ccs -h host --incversion
