K10 version 6.0.1

Hello @dhidalgo,

Thank you for using K10 community!

Could you please paste here the entire error message from the logs, it will give a better idea which resource is missing value could be storageclass of a valume or something else, you get error from run actions on K10 dashboard or try to grep it from executor-svc logs. 

Sure, 

I have enabled: Snapshot Exports. 

Choose Exporter Storage Class Name.

And here the logs, some sensitive data i have remove… :
