Image sync Main / Master node

[marcolefo]

Hi

I need help to understand the storage group function.
I would like to have :

• A main server with GUI and all image storage
• A storage group named SALLES-1
• A Master storage node of the group SALLES-1
• An image linked to storage group SALLES-1

In order to like in this doc :

I want to muticast in group SALLES-1. But I would like to have the image on the Main, in order to sync it with an other Master storage of an other storage group (SALLES-2 for example)

Is it possible ?

Thanks for your help
