Description Takayoshi Kimura 2018-12-20 00:59:50 UTC

https://docs.openshift.com/container-platform/3.11/dev_guide/expanding_persistent_volumes.html#enabling_expansion_pvc

Describe the issue: 

feature-gates ExpandPersistentVolumes=true needs both under apiServerArguments and controllerArguments but the example only shows apiServerArguments one.

> # cat /etc/origin/master/master-config.yaml
> ...
> kubernetesMasterConfig:
>   apiServerArguments:
>   ...
>     feature-gates:
>     - ExpandPersistentVolumes=true
> 
> # master-restart api
> # master-restart controllers

Suggestions for improvement: 

> # cat /etc/origin/master/master-config.yaml
> ...
> kubernetesMasterConfig:
>   apiServerArguments:
>   ...
>     feature-gates:
>     - ExpandPersistentVolumes=true
>   controllerArguments:
>   ...
>     feature-gates:
>     - ExpandPersistentVolumes=true
> 
> # master-restart api
> # master-restart controllers
