Thank you, Sir.
There was no action running that showed me reclaiming storage process was running. However after ten minutes, I saw in the home page of the admin GUI that the used storage was decreasing and after one hour the storage used by the received replicas has been freed.
So there is no need to open any ticket to support.
I'd like to give an idea: it will be useful to show the reclaiming storage process in the action running in order to notify the end user.
Best Regards.
