PLoecker commented on issue #339: Controller and invoker stuck after reboot the cluster

   Thank for your answer.
   
   I thought that could be the problem. I tried to set up a persistence volume, but I did not get it running.
   Because the server did not run on a cloud service, I think it is not able to use the dynamic Volume Provision.
   So I tried the local storage and created a storage class and a persistent volume. But now the CouchDB, zookeeper, kafka, and redis stuck in pending-mode. 
   
   I believe my master is not able to share his storage with the nodes. Can you help me to fix it or is there an easier solution to create a persistence volume?
   
   ### create volume
   ```
